Thermal

Thermal sensors detect infrared radiation in the 7.5 - 13.5 nm spectral band. All commercially available thermal sensors meant for use on a sUAS use an uncooled Microbolometer as the sensing technology. This technology has inherently lower pixel resolution than standard imaging sensors. Higher pixel resolution imagers are typically heavier, liquid cooled, and export controlled. This limits their use to larger aircraft and budgets.

Here are some examples:
