#infrared filter

[iwonderwh0]

Some android models definitely have infrared cameras, which makes them see for example when infrared sensors are at work as well as also see through some materials that infrared light can penetrate, like plastic. I don't think it's something all androids have despite it being a fairly cheap feature, like I don't think household androids like Kara do, but it can be handy for some specialised workers models, such as the ones Markus converts during the Capitol Park chapter in order to get access to what they're fixing to disable security.

Let me speculate and headcanon here that Luther, as a specialised worker of unknown original purpose, belongs to those models too and has infrared vision. Which means, he can instantly see the difference in how androids look as opposed to humans. Which would explain how He was able to instantly see that Alice is an android whereas as Kara couldn't do the same and saw her exactly as she'd have seen a human.

I think this headcanon works really nicely.

Protecting Polar Bears With Improved Radar Technology - Technology Org

Research testing new technology to more effectively locate polar bear dens across the Arctic is showing promising results.

Researchers from Simon Fraser University (SFU) and Brigham Young University (BYU), collaborating with Polar Bears International, hope that improving detection tools to locate dens—which are nearly invisible and buried under snow—will help efforts to protect mother polar bears and their cubs.

Results of a pilot study aimed at improving den location in Churchill, Manitoba—using ARTEMIS Inc., an imaging system that relies on Synthetic Aperture Radar, or SAR—are published in the journal URSUS just ahead of Polar Bear Week (Oct. 29 – Nov. 4).

The team found that SAR increased den detection by more than 20 per cent, or 66 per cent, compared with the industry’s current 45 per cent accuracy rate using the aerial Forward Looking Infrared (FLIR) system as a den-detection tool.

“Our airborne imaging radar system has multi-band, interferometric, and polarization capabilities at microwave frequencies able to penetrate snow,” says SFU engineering science professor Bernhard Rabus, who holds an Industrial Research Chair in Synthetic Aperture Radar. “The system can ‘see’ both the top snow surface, the den roof surface and inside the den cavity.”

“While our method is still in its research and testing phase, an operational version is expected to be able to extrapolate from the radar signatures of live bears in the open, combined with computer modelled den cavity radar signatures, to develop a robust match filter detection for airborne multi-channel SAR data to detect polar bears reliably inside their dens.”

Unlike aerial FLIR, SAR technology performs well regardless of temperature and weather conditions, which is crucial in the Arctic, thus SAR may be an effective tool to guide conservation efforts for this vulnerable and iconic species.

“This report advances Synthetic Aperture Radar as a promising method for polar bear den detection, which is critical for protecting polar bears alongside human activity,” says Geoff York, senior director of research and policy at Polar Bears International.

“Brigham Young University and Simon Fraser University have been invaluable research partners, and we’re excited about the possibility of SAR in the Arctic as it performs well in all weather conditions.”

David Long, electrical engineering professor and director of BYU’s Center for Remote Sensing, noted that the research provided BYU undergraduate Capstone students “an opportunity to do original research to identify and locate polar bears using radar. This is the first time this has ever been done, and we have great confidence this can be used in the Arctic areas to detect polar bears in the snow.”

Denning is the most vulnerable time for polar bears, and with increased industry activity in the region, there is a need for more accurate tools that can detect polar bear dens to avoid disturbing them during this critical time.

Polar bears cubs are born blind with only a light layer of fur to protect them from the cold. They remain dependent on their mothers, living in winter dens under the snow. They are able to emerge from the den in spring when they have grown enough to withstand the harsh Arctic conditions.

A mother bear’s inability to successfully raise cubs contributed to the 40 per cent decline of the Southern Beaufort Sea subpopulation between 2000-2010. A critical part of polar bear conservation is keeping mothers and cubs safe while also addressing other threats such as climate change.

"UV camera" is probably an inaccurate name. The camera is just expanding the spectrum it can capture to include UV.

The camera is still capturing the rainbow but it also captures a little bit into the purple. The more light reflected, the brighter the overall image. But if light is absorbed, it won't contribute to the brightness of the photo.

And since the sunscreen is absorbing a lot of UV light, their faces expose much darker.

You aren't actually seeing any UV light. Just the absence or presence of it making things lighter and darker. To see only UV light you'd need some kind of false color representation like predator vision.

A whlie back I was restoring a photo for a client and noticed a few people in the photo looked like they were donning black face makeup.

This didn't make a lot of sense because it was a team photo of an Australian rugby team from the 1930s and not a racist minstrel show.

And when I did my corrections, it turned out he was just a regular Aussie white dude.

I was initially very confused as to what was going on. But then I remembered modern camera sensors have a special filter to block any UV light that would affect the image. Cameras and lenses in the 30s did not have that technology and some film could expose beyond our visual spectrum—picking up a little bit of UV and infrared light.

Melanin absorbs UV light. Some white people have more than others. And so the young man in the photo appeared much darker than his teammates. In real life he was probably of similar complexion or a bit more tan. Maybe even sunburned.

It's also possible he was using rudimentary sunscreen. It was invented in the late 20s and I'm guessing athletes who were in the sun all day would be some of the first to be interested in sunscreen.

Another interesting effect caused by expanded spectrum cameras or black light photography—super freckles!

They are just dense spots of concentrated melanin.

Light is neat.

PAIRINGS: Vader x Rebel reader

SYNOPSIS: After a successful mission, things take an... interesting turn.

WARNINGS: Explosions, rebel activity, the Empire...

NOTES: In this AU the Mustafar duel happened but his legs weren't cut off. He still has burns around his legs and further down, not as intensively.

TIMELINE: next

「 Force 」

You stood upon the boulder, detonator in hand. Staring at the weapons manufactory, the stormtroopers filtering in and out. You felt yourself suffering from a crisis of conscience, and couldn’t for the life of you figure out why. These were people responsible for slaughtering innocent civilians, even the ones that followed the regime. They didn’t show mercy, not a sliver of it. So why were you here second guessing yourself about blowing this abomination to the ground? The mission report didn’t require you to evacuate the people inside. But you felt something tugging at your heart. Have they ever hesitated when it came to collateral damage? No…

But you weren’t them, and you didn’t want to be. You held your head up high, grabbing your datapad from your utility belt. Hacking into the Empire’s systems which was surprisingly not as difficult as you thought. ‘That’s what happens when you hire boneheads for IT.’ Shaking your head amused, despite seriousness of the current situation. You set off the evacuation, the alarms started blaring. Flashing red as the factory workers and stormtroopers alike started filling out of the building systematically. Sharing confused looks amongst each other as they made their way to the designated evacuation point. Grabbing your binoculars from your backpack you scanned the building in infrared. After making sure there were no heat signatures left inside. You pressed on the detonator, hearing the click before the building shook. Collapsing in on itself, catching light. Startling the Imperials as they took cover, shouting amongst themselves. Feeling the heat from the explosion reaching you even from your distance. You looked down at them, giving a salute. “For the rebellion,” you whispered. The words being carried in the wind, before turning on your heels. Heading back for your concealed ship. Allowing your footprints to be distorted by the wind, no trace of you left behind. At least you thought.

[ Meanwhile ]

Darth Vader is pulled from his meditation by a tug from the force. His piercing eyes snapping open, a gnawing feeling tearing through his gut. He stood up, his cape following suit. He stepped off the platform in his meditation chamber. Smoothing his hair back out of his face before grabbing his helmet that rested on its designated stand. The cold lenses staring back at him, a constant reminder of who he is now and the responsibilities that came with that. Sliding it over his head once more, hearing it click. Securing its place as the respirator flooded the inside with oxygen, he took a deep breath. Before exhaling, the sound resonating around the room. Giving an even more dramatic tone to his mere presence. He let his heavy arms fall back to his sides. The weight of his worries weighing down his toned shoulders. He took one last deep breath to centre himself, before exiting his mediation chamber. Heading for the war room, as soon as the door of his private chamber slid open. Vader was met face to face, well face to chest. With a lower level officer, sent to fetch him no doubt. To be notified about whatever had happened to cause such a disturbance in the force. The officer spoke up hesitantly, his voice trembling. “I- I’ve been sent to retrieve you, Ad- Admiral Tarkin wishes to see you in the war room.” Vader look down at the man, no older than his early twenties he estimated.

Not much younger than himself, not that he would know that. His mask was worn at all times in public, both the physical and the metaphoric one. So much so that who he was before he’d adorned it was a distant memory now, essentially another life. Without a word, Vader heads to the war room. Leaving the officer frozen in fear in his wake. The soft stomping resounded through the hallways, alerting everyone in earshot of his encroaching presence.

While Vader stalked down the halls of The Executor, his cape the colour of night. Billowing in his wake, the stormtroopers that were making their rounds quickly darted out of his way. The sounds of his respirator echoing through the halls, and ringing in his head. A ringing he’d grown used to, it’d become background noise. While there were many things he hated about the suit. In moments like this, he appreciated the anonymity. Though deep down, in a corner tucked in his mind. He knew that was only part of its purpose. The costraphobic layers, served as a reminded. A reminder of his duty to the Empire, to Sidious. And of the betrayal that led him here, the scars he’d gained in consequence had faded. But still clung to his skin, digging their way into his very soul. What was left of it at least, taunting him. Of what he’d done, who he’d hurt. Betrayed, the lives he’d taken, and those that followed-

“Lord Vader,” the voice of Admiral Tarkin greeted him. His gaze shifted, looking up from his position in the doorway. To the Admiral, his gaze flitting to the projection lit. Exposing the damage to the manufaction plant, the hologram rotating slowly. His body was on autopilot as he stepped closer, analysing the image in front of him. “As you can see, the weapons manufactory plant has been completely levelled. No personnel were lost, an evacuation alert went off prior to the explosion.”

“Who set off the evacuation?” He questioned shortly, his words eerily even.

“Unknown. The perpretrator was able to compromise our systems, initiating the evacuation before the building was destroyed.” Tarkin’s words became a blur to Vader, his mind racing. As he felt that feeling from before tugging at his gut. He continued to stare at the projection, ‘this was a suspected rebel attack. But the MO is different, why evacuate the building if it’s supposed to be a message against the Empire? Why go through the effort of evacuation?’ He thought, crossing his thick arms over his chest.

「 You 」

I watch the ramp to my ship lower, and I took a deep breath. Steadying myself as I walked up the ramp, heading for the control panel so I could get out of this shit show as soon as possible. Something was… different. I couldn’t quite put my finger on it, and that’s what’s worrying me.

I heard the whoosh as the ramp door closed. I start the engine, taking off slowly and steady. Keeping the noise down to a minimum, even though the factory was destroy I didn’t want to push it. After exiting the atmosphere I prepare to jump into hyperspace. I wrap my fingers around the lever, gripping it tightly-

I can’t see anything, blinking rapidly. Suddenly blinded by fluorescent lights, slowly the room comes into focus. Something rotating in front of me, when my eyes focused. It was a blueprint… to the manufacture plant I just blew up. Shivers climb up my spine as I hear a deep inhale, that sounded like a machine… or a man? “Hello little minx,” I jolt in surprise. The voice lingering in my mind.

“What the fuck…” I whisper. My eyes darting around, I’m back in my ship.

WHAT IS THE LYMPHATIC SYSTEM?

think of the lymphatic system as your body’s emotional janitor and drainage crew. it’s part of your immune system, and it does the following:

• filters waste, toxins, and pathogens

• moves lymph (a clear fluid) through your body

• helps circulate white blood cells

• absorbs fats from your digestive system

• balances fluids in your tissues

it’s made up of:

• lymph (fluid)

• lymph nodes (filter stations)

• lymphatic vessels (the pipelines)

• spleen, thymus, tonsils, bone marrow (support squad)

your heart pumps blood, but your lymph has no pump. it moves through muscle movement, breath, and manual stimulation. no movement = no drainage = sluggish, bloated, toxic vibes

WHAT IS LYMPHATIC DRAINAGE?

lymphatic drainage is the process of stimulating lymph flow to help it do its job faster and more efficiently. this can be done manually with massage or with tools/devices. it’s like giving your internal plumbing system a nudge.

benefits?

• reduced swelling/inflammation

• glowing skin

• decreased bloating

• boosted immunity

• improved healing post-surgery

• less brain fog

• reduced cellulite appearance

• de-puffing (hello, snatched face + jawline)

WHY YOUR LYMPH SYSTEM LOWKEY RUNS YOUR LIFE

when your lymph is stagnant, it doesn’t just affect your body it affects your mood, energy, skin, digestion, even spiritual flow. (yes, your energy field has drainage, too.)

poor lymph flow can lead to:

• chronic fatigue/ laziness/ procrastination

• frequent colds/infections

• puffy face or limbs

• brain fog

• digestive issues

• poor healing

• acne + skin flare-ups

• fibromyalgia or pain syndromes

this is your sign to stop ignoring your lymph.

SIGNS YOUR LYMPHATIC SYSTEM MIGHT BE CONGESTED

• you wake up puffy AF

• you get sick a lot

• your skin looks dull or acne-prone

• you always feel bloated or heavy

• your eyes feel heavy/tired

• you have sinus issues

• your underarms or groin feel tender (lymph node overload)

• water retention that won’t go away

TYPES OF LYMPHATIC DRAINAGE

A. MANUAL LYMPHATIC DRAINAGE (MLD)

• slow, rhythmic, skin-stretching strokes

• developed by Dr. Emil Vodder

• done by trained therapists or at home

• moves lymph from extremities toward nodes

B. MECHANICAL DRAINAGE

• compression suits (like Normatec)

• vacuum suction (like LPG Endermologie)

• electric rollers + vibration plates

C. INTERNAL (NATURAL)

• breathwork

• rebounding (trampoline bouncing)

• dry brushing

• sauna/sweating

• hydration

• movement & inversion yoga

HOW TO DO MANUAL LYMPHATIC DRAINAGE AT HOME

PREP:

• be well-hydrated

• be relaxed (stimulating lymph in stress = nah)

• use a dry brush or clean hands

FACE:

1. start at collarbone, gently massage down and out

2. jawline → ears → down neck

3. under eyes → temples → down sides of face

4. forehead → temples → behind ears → down neck

5. always drain downwards toward collarbone

BODY:

1. start at armpits

2. stroke down from arms to armpits

3. belly massage in clockwise circular motions

4. groin lymph massage with gentle circular movement

5. legs: ankles upward to thighs, ending at groin

tip: Always go from distal to proximal, meaning far-to-close to the heart. And be gentle lymph is superficial, you don’t need deep pressure.

DEVICES THAT CAN HELP

for the face:

• gua sha (natural, ancient, sculpting goddess magic) (i use this)

• jade rollers (cooling and de-puffing)

• Foreo Bear or NuFace (microcurrent tools)

• ice globes (i use this)

• vibrating massagers (i use this)

for the body:

• dry brushes (firm bristle brush for exfoliation + flow) (i use this)

• lymphatic paddle boards (i use this)

• compression boots (used by athletes + lymphatic clinics)

• vibration plates (you stand and it shakes your lymph awake)

• infrared sauna blankets

• LPG Endermologie machines

LYMPH-FRIENDLY LIFESTYLE HACKS

FOODS:

• raw fruits (pineapple, berries, citrus)

• leafy greens

• ginger + turmeric

• dandelion root

• seaweed

• chlorella + spirulina

• omega-3 rich foods

HERBS:

• red clover

• cleavers

• echinacea

• astragalus

HABITS:

• drink water (especially warm lemon water)

• move daily (walk, yoga, stretch)

• alternate hot + cold showers

• dry brush before shower

• rebound on mini-trampoline

• sleep well (drainage is boosted in deep sleep)

LYMPH + BEAUTY

• lymphatic drainage de-puffs the face like magic

• stimulates collagen production

• clears breakouts by boosting detox

• reduces dark circles

• tightens jawline and cheekbones

• boosts skincare absorption

SPIRITUAL + ENERGETIC LAYER

in many healing traditions (like Ayurveda, TCM), lymph = life fluid. congestion = blocked emotional energy

blocked lymph = blocked creativity, blocked intuition, blocked glow.

draining the lymph = restoring your internal flow, your connection to Self, Source, and spirit.

you wanna shine? clear your waters.

HOW OFTEN SHOULD YOU DO LYMPHATIC DRAINAGE?

• face: daily or every other day

• body: 3x a week minimum

• post-op: depends on doctor’s advice

• vibration plates/compression boots: 15–30 mins a few times a week

CONTRAINDICATIONS + SAFETY

don’t do lymphatic drainage if:

• you have active cancer

• you have infections or fever

• you have blood clots or deep vein thrombosis

• you are pregnant (only do under supervision)

• you’ve had heart or kidney issues (speak to a doc first)

always listen to your body. gentle is good. pain is not.

FINAL WORD

your lymphatic system is like your inner spa therapist, immune defense squad, and emotional sponge rolled into one. don’t sleep on it.

if you want:

• snatched cheekbones

• less puffiness

• glowing, radiant skin

• fewer colds

• balanced moods

• deep detox

• emotional flow

then lymphatic drainage isn’t optional. it’s essential. give your body the love, movement, and flow it deserves.

NEVER buy laser pointers on Amazon

The laser pointer in this post was being sold as "eye safe". Specifically a class 3R, which is <5 mW in the visible spectrum, safe for casual use because your blink reflex protects you but not safe to stare at.

It would actually:

Ignite flammables meters away

Permanently damage your eyes at over a 100 meters faster than you can blink

Flash blind drivers at half a kilometer

NEVER buy laser pointers off of Amazon.

Also, you can't trust how bright a laser pointer seems to be. The light in laser pointers is often generated in the near-infrared at 1064 nm or 1270 nm, then "frequency doubled" (two photons of long wavelength are combined to make one photon of half the wavelength) to get 532 nm (green light) or 635 nm (red light). If the conversion is inefficient and the manufacturer cheaps out on the infrared filter (horrifyingly common), it can generate many times more invisible infrared light than the visible light you're seeing. And that invisible light will damage your eyes just as readily as the visible light (worse actually, because it doesn't trigger the blink reflex). So again-

NEVER buy laser pointers off of Amazon.

Random Transformers Headcanons

transformers can see more colors than humans can. Cameras use something called the bayer color filter, which is a grid of red green blue squares that is taken and pixelated- by the same principles, optical sensors could have multiple color receptors (like add magenta and yellow)

Bots with more than two optics can pick up more colors (shrimp vision). Empurata victims lose color receptors in their optic, reducing vision to standard RGB

Depending on modifications, can see in UV, infrared, heat vision, etc. Earth is a sensory overload at times.

Giant seekers like shuttles and space stations sing in ultrasonic waves, often to communicate and identify, as each has a unique song. They're space whales :D

Some bots have UV paint lines on their armor that glow under certain conditions/in response to their spark feeling strong emotions. Could've been an old fashion fad or simply exposed energon nerving in their plating.

Most bots do not have true gray colored plating- it resembles too close to a dead shell and sometimes, some bots are taken to smelting pits because of this. The most common bots to have gray paint are miners and gladiators because it hides debris and injuries better, but also because it keeps them from having any individual identity. Megatron keeps his gray colors to honor his time as a miner and gladiator.

Seekers only stay to their trines/sparklings when sleeping, but ground alts often seek out large groups for security. When grounders are in new environments, often there will be one bot on watch and the rest huddled together at the camp ground

The lost light actually separates bots because of Magnus being an ass and not understanding sleeping dynamics cause it's been so long since he had his brother

Shuttle bots and larger prefer to sleep in their alt modes with their occupants safely tucked away

(last headcanon inspired by an instagram reel I saw by astragirlxx about sleeping groups of autobots)

That's all I've got for now!!!! :DDD
