fyi, mosquitos have terrible eyesight and only use it for the last few meters I believe. They do track carbon dioxide, living things breathing so a food source, and scents.
Glory? My head canon for the Predator is that they are dentists or rich guys from another system that are looking to get a safari/big game kill so they can lie to their friends. This is why they die whenever they meet someone with actual skill. Sure they can kill untrained primitives, wolves, and whatnot with their fancy tech; but an actual foe who sees what they are? They are toast!
They really are quite pathetic. Sure they're strong as heck and can be invisible, but a little girl killed one.
You just described doing something for "glory": So you can brag to your friends about the amazing, dangerous, difficult thing you did. And killing an almost invalid creature isn't going to be very "glorious".
ah, I see what you're saying! Yeah, lying can lead to glory. I guess I was thinking more in the second way, where they are basically killing an almost invalid creature then claiming it as a glorious battle. If you are invisible and then shove a spear through someone, it doesn't matter if they have a gun, they have no way to know you are there. It would be like some spec ops person fighting a random caveman. Not really glorious. But you do get to increase your k:d rations.
I'm fascinated by the fact that heat can reflect off surfaces, as seen in the video. I always thought that, once radiation goes into the infrared spectrum, it's sort of "unmanageable" and just gets absorbed, but apparently you can take "heat" and just reflect it out a window from your home if you're tricky.
Nope, bounces pretty good. It's even so good that it's hard to take IR thermometer measurements of shiny objects. You end up taking the temperature of the reflection instead. This is also why you can turn on your TV around corners or bouncing it off the ceiling.
IDK if I'm asking the right person, but IR is a pretty wide range, right? Is 'heat' in that entire range, and is it possible to reflect stuff in the entire range?
Light is light. Radio waves can be reflected and that's below the IR spectrum. X-rays can be reflected and that's above visible. "Heat" produces light of all wavelengths from the microwave background radiation of ~4 Kelvin to beyond visible.
It DOES feel weird, doesn't it? But infrared radiation, which is what thermal goggles see, is electromagnetiv radiation, just like visible light, it behaves the same. It just so happens to be outside the wavelength area our eyes can see.
I REALLY wanted a night-vision device ever since I was a kid. I know I’d probably never use it, which is why I haven’t bought one yet but it just always seemed like such a cool spy tech item
I borrowed one for imaging my house for insulation problems, would love one like they've got here, but they're going to be insanely expensive and I don't really have anyway to justify that kind of expense on a toy!
They are very excellent for picking up your dog's poop when it's cold and miserable out and the dog decides to use the darkest part of the dog park to do its business in.
i got to play with night and thermal optics a while back. 1) its an absolute superpower to see at night and 2) if you don't have it, you're at a serious operational advantage compared to those who do.
I got to use a set 20 years ago in combat school and they were pretty neat. One thing no one warned me about was how it was monocular so I had zero depth perception and it was rather difficult walking in the woods that way.
are there reasonable consumer-grade ones? I go hiking, sometimes at night, and am very curious to learn what wildlife is around me that I otherwise cannot see
You can get a kinda decent thermal camera for less than €300. This is shaped like a compact camera, so no sights or closed opticals, just a small screen.
They are considered old school now but camcorders are surprisingly good at seeing in the dark. They project an infrared light which their optics easily pick up and display. In a combat scenario this would be horrible though. The infrared light would be a beacon to anyone with good optics.
No, mylar blankets do not work if it is anywhere near you. The reality is that those blankets are so thin that basic human body heat emissions will warm the blanket within minutes to give away your position. How do I know this? This gif is from a youtube channel that does demonstrations. If you've thought of a way around it, they have shown how it won't work.
Thermal mass is the only solution. Dig a deep tunnel and hide in it. Even walking in snow will give away your trackable movements.
I've seen them work while hunkered down in the snow, but I think they may have layered them as well. There are always ways to defeat tech, but it does get harder and harder. I suppose the other option at this point is flares :)
/oh and I did say mylar works at first but your body heat will warm it quite quickly. That's the problem with most of these things, if it touches your body, then you will warm it. And the thinner the material, the faster it warms.
As I already said, yes, mylar can reflect heat but it takes nearly no time at all to warm the thin blanket so it is functionally useless. So if you're looking for something that will block thermal scopes for 5-10 seconds then it's fine to cover yourself with it. Hold it a foot or two away and you'll have a few minutes because your breath is enough to warm it. But then you have to create a larger structure to cover more angles, which creates a blank spot which also gives you away.
I'm not looking to block thermal scopes, I was mostly trying to assure people thermal blankets can still help in emergency situations and so "work" as intended.
I fully agree they don't work at all for thermal scopes. However for an emergency situation that is a good thing, rescuers can and have used thermal cameras to help locate lost people.
LutraLazuli
My dad spoke of using what he termed "The Cyclopes" night vision goggles. The one he used was the light amplification one, not thermal.

TrumpRapesAndEatsChildren0002
Depends on how rich said 'consumer' is. Stuff's expensive if it's supposed to work. Thermal rifle scope ~$4k.
honeybadgersRus
You can get them starting around $500 but it's kind of shit till you spend 1k+
If you drive to shop around for one
256x192 is the minimum functional baseline. Anything lower just shows hot blobs.
You need at least 30Hz for tracking moving wildlife.
Thermal Sensitivity needs to be <40mK.
Narrow angles cause tunnel vision. Prioritize wider angles for scanning campsite perimeters quickly
