Interesting. As a FLIR camera used to be expensive, I built my own thermal IR camera for $120 (2011): http://oi60.tinypic.com/2820yg2.jpg

Do you have a tutorial?
Sorry, not at the moment. I am using an Arduino, two servo motors, a medical grade thermal IR sensor with a small point of view and a webcam, all connected to a notebook. Shooting a thermal picture takes up to 60sec, so it is not completely comparable with a IR-CMOS that FLIR cameras use, but a lot cheaper and the measured temperatures are more precise.
Probably a scanning IR thermometer. Not really the same thing...
you are right, well almost. I am using not an IR thermometer, but medical grade IR sensor. But you can reuse an IR thermometer too (with a bit lower grade results).
