Very little attention is placed on high speed thermal imaging because frankly it’s a field so new that only a handful of cameras can even approach that performance. The FLIR X6900sc is breaking records by now recording 1000fps at 640 x 512 resolution which is pretty high by thermal pixel standards and a memory buffer recorded on-camera RAM for 26 seconds.
Thermal imaging uses unit area sensors which correspond to arrays of pixels to form the full image. These have to be sensitive to radiation in the long-infrared range of the electromagnetic spectrum (roughly 9,000–14,000 nanometers or 9–14 µm) and produce images of that radiation, called thermograms.
These thermal cameras operate very differently from night vision IR cameras as the temperature scale and wavelengths vary greatly. You can read more about it here.

While no pricing details are available you can visit FLIR’s X6900sc page and ask for a personalized quote if you are so inclined. Thermal cameras are not cheap and this one being state of the art will probably be out of the reach of many. Still the technology steps in high speed thermal imaging are encouraging enough that a slow motion capable thermal solution will probably be introduced at an affordable price bracket.
While the high speed thermal field is pretty new, you can already see very useful applications like air bag deployment, aircraft stress testing and car performance heat dissipation. High speed thermal imaging will only get better from here.
