I'm inclined to believe the FLIR One does not use "true" infrared. There's a portion of the visible spectrum that is nearly IR and it's possible to rely on some IR reflectivity phenomena. I looked at some other FLIR thermal cameras and found them to be much more expensive; thousands of dollars. However, there's no doubt a small mobile platform is very usable. The primary goal behind this work was not to make a product: it was to provide a proof of concept. We were interested in the image processing and showing that some heavy lifting could be done on a small mobile platform (the Raspberry Pi). You are correct about the acquisition rate. However, the acquisition rate was more limited by the motors to move the sensor into place.
