Great explanation of where infrared falls on the visible spectrum. Your demonstration o the door shows it's important to remember this is not x-ray vision. In the technical side, I can see customers using this in a hunting application get confused when their rabbit or deer disappears behind thick brush or a large tree trunk.

They are friking AWESOME!!!! I absolutely love mine (I also love going on night hikes). I will forwarn you these are definitely not cheap, but for around $2000.00 you can get a pretty darn good one just do your homework and ignore screen resolution (it will be like 1080 screen resolution) but you want the microblometer resolution instead (that's what detects the thermal radiation) your image will only be as good as that resolution. Unfortunately they like to trick you with high screen resolution despite it making no difference as long as it's at or slightly above the microblometer resolution. I/e flir has a 1080p screen but only gets 320 for the microblometer. Moreover check out pulsar there way less money for way better imiging.

Yes, but it's not nearly as visible. When he does the dry ice test and you see the foggy shimmer its actually the cold air being picked up by the thermal. Granted if the temperature is not huge it's very difficult to see, but I have seen farts, car exhaust, dryer vents, ect. It kinda looks like how you see with the naked eye thermal heat waves in the summer.

Yes and no depends on the inferred spectrum, near inferred (what you are talking about) is so red you almost or if further along can't see it with the naked eye, this is the same technology your TV remote uses (hold your remote up to your camera on your phone for example). Anyway thermal inferred is generally much further along on that spectrum you can see it if it's hot enough (think catalytic heaters for example) but generally it can only be detected via a thermal imaging unit as a regular camera can only see the near inferred spectrum as such near inferred doesn't show up on thermal either.

However, it is definitely something that is being discussed. Stay tuned.

Frankly a space blanket can easily block thermal, basically anything that stops the thermal radiation from passing. The issue (if your trying to hide) is that the space blanket will look super out of place itself, granted you wouldn't know there's somebody behind it as long as it's not touching you or the heat source, but it would reflect the surroundings acting like a mirror, moreover if you're outside it and it's angled up it would show up as very cold (just like car windshields do) as it would reflect the coldness of space. So if you were hiding and I looked through the thermal at you I would see an extremely dark square, my own reflection, or whatever is in front of the blanket, glass, ect.

I notice that pilot videos with UAPs go dark around the object once they switch to thermal. Does this mean it's really cold?

do we have a thermal paint that enhances capability of my thermal camera as I place my object (painted) far away from it ?

@IAM_GhosT1

Жыл бұрын

Yes there is thermal paint, it's designed to reflect space / cold and is aimed at an upward angle or on roofs. It doesn't have to be angled as such but basically acts as a mirror and will reflect the thermal inferred radiation, for example if you aimed it at trees then looked at it it would reflect the trees.

So those reflective insulating material we see on the inside of jackets, if we turned that inside out, theoretically we wouldn't be able to see the jacket because it's reflective?

Pulsar is much better than flir, so if you want to buy a thermal unit look at the microblometer resolution as the screen itself can be 1080+ but if the microblometer is 120 you will only get a 120 resolution. As the microblometer is in essence what detects the thermal radiation. If you really want the best in a handheld go with trijicon as they have the highest thermal resolution (you will pay very dearly for it) pulsar comes in second at 720p and flir is half that. Alternatively if your rich you could buy a cooled unit (like the police choppers use) in that case flir is the best but your talking a few hundred thousand dollars at that point.

Polycarbonate is not very opaque to most wavelengths of infrared, so it would not be a good choice.

That's why I didn't go with flir, mine sees the different temp of water in a silver can. Anyway I didn't come here to bash flir, I wanted to mention that you never mentioned my favorite part about thermal imaging... You can see through a tarp or plastic garbage bag almost unadulteratedly, theres a slight shimmer of the bag giving off it's thermal radiation but beyond that you can see through it pretty well, the closer and hotter the object on the other side the clearer the image through it, (this also works with very thin clothing). The downside is if your trying to walk you could easily not notice the plastic sheeting. Also a fun fact you can see hot/cold gasses like your dry ice test where you see the slight whisps of the cool air so you'll know who let it rip if you happen to be watching with the thermal. Last but not least despite not seeing through glass (it can't because as you mentioned it sees the surface temperature) if you were to touch the glass on the side away from the thermal for long enough your handprint would eventually bleed through and could be detected, for those who don't understand it's because of heat transfer that warms up the glas in that spot essentially warming it enough that the other side gets warm enough to detect. Beyond that the points you talked about are spot on just figured I would add some info that I had wondered about for many years (until I dropped the multiple grand it cost to purchase one and find out). If this comment gets idk 20 likes I will post a video showing more fun things utilizing a 720p thermal microblometer (the thermal sensing chip). Oh and one last fun fact, the original thermal imaging systems required liquid nitrogen to operate and were upwards of $80,000.00 that is until the microblometer was invented as the chip itself is in a vacuum allowing it to detect the thermal inferred radiation / aka heat.

I'm not buying that explanation for the two metal cans. It's not the reflected IR that's directly important, it's that they they have low emissivity and therefore don't reveal their temperature.

Fog does NOT obstruct thermal but Co2 does (dry ice is Co2) Many hunters use it because of they can see everything in the fog

@ddegn

Fog does obstruct thermal radiation. It's just that fog blocks visible light better than thermal radiation. The video shows the thermal camera sees though the fog much better than visible light camera. It's possible to detect CO2 with a thermal camera but the effect is much much weaker than the effect from fog. It would have been interesting to see if the thermal camera could have detected CO2. Usually a special filter is used when detecting CO2 since it's much harder to detect.

Fog can affect thermal, if the fog is thick enough it will limit your range and details of the object you are looking through the fog at as much like a blanket it does absorb some of the heat. The dry ice was more so in the fact that it's giving off cold. I am a hunter and I have a thermal.

How to defeat it

Thermal radiation and infrared light are two different things that happen to share a frequency range most of the time. Infrared light will pass through glass, whereas thermal radiation will not (or at least not enough to easily detect). Which is why you can't use a lens to focus a thermal imaging CCD. The CCD must itself be shaped to the desired focal length. Hence the high cost...

@adalovelace95

6 жыл бұрын

Nope.. it's the same. Infrared is a bandwidth from about 800nm to 1000um. Thermal Radiation has a certain wavelength depending on temperature and can be even outside of IR-range (See Wien's Displacement Laws)

@MatHelm

6 жыл бұрын

No it's not the same. In fact a thermal CCD is colored to block any and all light. Hence the clear glass blocking it. Infrared light of course passes freely through clear glass. And with ambient Earth temperatures being what they are, most of the thermal radiation will be in the infrared wavelenght spectrum (700 to 1000nm). But no, a thermal CCD is not limited to that spectrum. But the programming used to generate an image is looking for differences in thermal radiation from one pixel to another. It's not simply reflecting the state of pixels as a normal CCD does.

@adalovelace95

6 жыл бұрын

Hmm.. not sure what you mean. Please note, I said 800 Nanometer to 1000 Micrometer(!). Yes, there are special CCDs but they're not just colored black or have a special shape, they're made of other materials (e.g. Iridium or Gallium instead of Silicon). Thermal radiation IS the same physical thing as visible light, infrared, UV, gamma, microwave, radio and so on... --> electromagnetic waves, the only difference is the wavelength. But "normal" temparatures on earth are lets say -50 to 150C which is about 7 to 14um. 700-1000nm would be about 2500-4000C, which is quite unusual for most thermal imaging applications.

There would be no difference, as the thermal wouldn't determine different colors so white black ect would look the same, now there's one thing that would change this being exposed to sunlight. Obviously the different colors would absorb different amounts of heat from the sun and in turn would give off different temperatures accordingly. If using white or black hot (my unit only has those options) it would show up with almost all no difference for the white tape and would show up as hotter for the black tape. Moreover different types would react differently as the material would absorb the temperature differently.
