I got some new toys to play with recently, some thermal cameras. Smallest one is about 1-3/8" at it largest diameter and about 4" long, it uses a uncooled 320x240 sensor. I took this pic of a motherboard with it:
Next on is the big brother to the little one, it uses a 640x480 uncooled sensor. It snowed this last week here so I shot some video outside:
And last, but not least, is a 640x480 camera made by FLIR. This one is a bit special. It uses a stirling cycle cryo-cooler to drop the sensor temp down to 77K. great sensitivity, they use the same imaging for, video processor, and optic train as in the Recon III binoculars which cost over $80,000. Pretty neat, it outputs in composite, VGA, and HDMI. Unlike the other cameras which just output raw monochrome video, this does the whole false color thing. Pretty powerful video processor, uses two Vertex 4 FPGAs and a PowerPC to drive it.
