Point of order: Image intensifiers are generally near-IR sensitive. (a ~ 940 nanometer (a wavelength ~300 terahertz) IR LED is used for your TV remote and is also used for active illumination for image intensifiers. Thermal cameras have a number of different detection modes. The common one is bolometric detection: It measures the magnitude of the heat produced rather than the luminosity. (The difference in methods is like the difference between "seeing" an LED light (Intensification) and "feeling" an incandescent (Bolometry) light)

The detector is designed to pick up light from either a reflective object (visible, SWIR) or an emitting object (MWIR and LWIR). Planks law help guide you choose which bandpass (and detector response) of light you want for your application. For instance, objects at room temperature have peak emission power somewhere in the LWIR.

The good ol "Sony Nightshot" feature. If I remember correctly, it had a button thingy that pulled the IR filter out of the way and lit some IR LEDs. IR filter is there usually because the IR light that is nearly invisible to human eyes, triggers all 3 colors on a ccd sensor and really messes up the colors on the final image.

You missed out on one other method- buying a a7s ii and cranking the iso

speaking of night vision in gaming, in GTA V in one of the missions (spoilers, by the way, if anyone cares, i'll spoil one of trevor's missions and an easter egg, so don't read any further unless you want to) in that mission where the o'neil brothers (or whatever they're called) are trying to get to trevor and franklin follows them, and then they drive off the road, you get to use a sniper rifle with an infra-red scope to find where they are so that you can kill them, in the first few seconds of using the gun you can find bigfoot's heat signature just standing there, and then it slowly fades away. freaked me out a little bit when i played for the first time, i have to admit. i just wasn't expecting it, that's all.

You can adjust the temperature range that the device sees. So basically the person would appear on the coldest end, and the fire would appear on the hottest end. Imagine it the same way as if you were to see a person holding an ice cream cone. It's not like you wouldn't be able to see an ice cream cone. It would appear black against a bright background.

You guys should explain how full color night vision works, was hoping to see that covered here but I'm sure that it would take longer to explain and/or there isn't enough public information available to explain it (I know it's a rather new and militarized technology). Either way, the video was great!

The only downside to thermal imaging, is you have to constantly adjust your camera. I always thought you just pointed it, but then I ended up taking a thermography certification course for a job I was getting and found out it was way more complicated. There are hundreds of things you need to compensate for. The photons generated by heat can reflect off of certain materials, and give you a false reading in a process that I haven't fully wrapped my head around. Look up the wikipedia page for "Emissivity" If you're that curious, it has a picture which can explain it much better. Long story short, actually operating a thermal camera isn't as fun as it looks, because you constantly need to be messing with your camera's settings if you're on the move by any slight degree. Edit: And to top it off; no there isn't actually any thermal imaging for your phone yet. Any apps or addons so far have only be NEAR infrared. But not true infrared. Meaning it's little more than a novelty. You couldn't use it for very many practical applications.

Techquickie on cameras, i'm thinking the difference between sensors (full frame, crop sensors etc) Possibly lighting? why you should choose softboxes over umbrellas and vice versa.

He probably should have added that most cameras without a filter can see in the ir spectrum too, which is why your phone camera can see the led on a tv remote flashing. This is useful for security cameras since they can have a spotlight of ir leds which won't shine in people's faces, making them more stealthy and less annoying while also illuminating the camera's vision.

I wish there was like, a device that emitted light so that when you pointed as something you could see what it was in the dark.

There is a very high voltage applied between the photocathode and the MCP, and between the MCP and the phosphor screen. This accelerates the electrons which remain collimated the whole way through. In a lot of tubes there are also electrodes designed to focus this stream of electrons onto the screen or even invert the image entirely.

woah, luke really NCIX'd that end up big time.

Imagine how much of human progress had to be made for this invention to exist

Is it made with ir light and ir cam's

so is it impossible to see when there is no light and no heat?

You guys mixed up near infrared and far infrared. Far infrared, which is what thermal cameras see, never work with active illumination, because that would essentially mean radiating thermal energy. Not very practical, except maybe in a campfire situation and it would decrease the image definition instead of increasing it, as it wold be absorbed by most materials instead of reflected. Near infrared is the part of the infrared spectrum that is close to the spectrum of visible light and that works with active illumination, usually with infrared LEDs like you also find in your remote controls, which is why many camcorders - especially those with an optional night vision mode - will actually see the light your remote is emitting. Both don't really have much to do with one another, near infrared is behaves like visible light and is actually visible to all modern CCDs. Cameras have to actively filter out near infrared with optical filters, so it doesn't distort the light distribution in images, so security cameras are just regular webcams with the near infrared filter removed and often optional infrared leds.

most phone cameras can see infrared light. like the light that comes out of a TV remote (try it). so if you have an ir lamp.

Great video but you made the point that thermal imaging is able to see infrared. Technically both image intensification night vision and thermal imaging both detect infrared. The thermal imaging uses a sensor to detect radiation (upper portion of infrared) and night vision amplifies the ambient light (including the lower portion of infrared). Sorry I'm a dork.
