user=ID10T, in this case...

Though I wonder one thing: one vision mode is obviously visible light, which was right to be blinded by the laser. However, the other seems to be thermal/FIR imaging(based on the fact that it showed the two guys even in pitch blackness as white shapes, which NIR is unable to do(speaking from experience, I made myself a near-IR imager webcam :) )), which, afaik, should not be jammed by a green laser, right?

Correct me if I'm wrong, though...

It's a thermal cam mode ..... they're filtered for block anything except far heat radiation, so also the IR part that the laser eventually produces ..... the image is generated from the heat, not from the light, so it's not influenced from the laser, as you can see when they switch the two images, also when they're aiming at the camera (that turn down aperture in automatic), the thermal camera don't show the beam.

don't green lasers have an IR filter to remove that part of the spectrum from the final output?

Thunder, I think you're right that it won't jam the thermal/FIR imaging. To me it looks like they were pointing the laser at the chopper the whole time in the beginning, we just saw the green laser so brightly when they were switching between the two different camera types.


EDIT: yes they do have filters, but depending on the quality of the filter a lot or a little IR is still present

But the thermal imager blacks out too after it switches back from visible light, which it should not do...

808/1064 is nothing close to the wavelengths detected by a FLIR.

Cause it's a thermal cam, not just an IR cam ..... different wavelenght, so all the near IR are blocked from the filters, and don't affect the image generated from the thermal cam ..... just as example, see the front part of the car in the thermal image, it look incandescent, but probably it's just some degrees more heat of a human body.

Some of those military-level thermal cameras can draw your image from the difference of the temperature between your body and the background of only HALF CELSIUS DEGREE ..... (if only i can get my claws on one of them, slurp :drool: :eg:)

EDIT: sorry, just forgot to specify, usually the wavelenght that are interested for thermal (so-called FLIR) cameras are between 7.000 to 14.000 nm

my car has a thermal cam and it looks just like that. and the. its really cool. it sees everything. the mountains in the distance little animals even the paint on the road. it's made by Raytheon. no lights affect it. i tried both my red and greenie.

The Thermal camera in your car.... was that an after market product...:undecided:
If so... so you have a link or name of where to get one...
If not in what make/year/model of car is it in....:)
