I had an engineer at my inspection yesterday. He tells me FLIR is an acronym for Forward Looking Infrared.

Forward looking infrared (FLIR) cameras, typically used on military and civilian aircraft, use a thermographic camera that senses infrared radiation.](https://en.wikipedia.org/wiki/Forward_looking_infrared#cite_note-1)
The sensors installed in forward-looking infrared cameras—as well as those of other thermal imaging cameras—use detection of infrared radiation, typically emitted from a heat source (thermal radiation), to create a “picture” assembled for video output.
They can be used to help pilots and drivers steer their vehicles at night and in fog, or to detect warm objects against a cooler background. The wavelength of infrared that thermal imaging cameras detect differs significantly from that of night vision, which operates in the visible light and near-infrared ranges (0.4 to 1.0 μm](https://en.wikipedia.org/wiki/Micrometre)
Your engineer friend is correct.
FLIR is a military acronym for Forward Looking Infrared. When it first came into use the term applied to fixed-mount thermal imaging systems that were carried on aircraft. These early thermal imagers were attached via stationary mounts that did not allow for the thermal imager to be articulated or moved. Hence, early FLIR systems were positioned to look forward and/or downward of the aircraft on which they were attached.
Outside of the military one may hear the term FLIR applied to thermal imagers used for surveillance, law enforcement, and search and rescue. In describing modern vehicle-mounted thermal imagers, the term FLIR can be a misnomer especially when it is used to describe gimbal type imaging systems which can be rotated 360° horizontally and 180° vertically.
FLIR is also the NASDAQ symbol for FLIR Systems, Inc. a company that makes a wide range of thermal imaging systems.
Hope this helps.
