How does FLIR technology primarily operate?

FLIR technology, which stands for Forward Looking Infrared, primarily operates by detecting thermal energy emitted by objects. This technology is designed to sense infrared radiation, which is a type of energy released as heat from all objects, including living beings and vehicles. By detecting variations in thermal energy, FLIR systems can effectively create images of these objects, even in low visibility conditions such as darkness or adverse weather environments.

This capability makes FLIR particularly valuable in military and surveillance operations, where traditional imaging systems may be hindered by visibility issues. The images generated by FLIR can provide critical information about the environment and the objects within it, enhancing situational awareness and decision-making.

In contrast, the other options refer to different technologies that do not apply to how FLIR operates. For example, using radio waves pertains to radar systems, analyzing reflected light relates to optical imaging, and sonar is used for underwater mapping and detection. The core functionality of FLIR is distinctly based on thermal energy detection, reinforcing why the chosen answer is appropriate.
