The PAS 25/28 is used as what kind of device?

• A. A thermal imager
• B. A laser range finder
• C. Night vision device
• D. A communications unit

Answer: (A)

Thermal imaging is the capability PAS 25/28 provides. It detects infrared radiation emitted by warm objects and converts that heat into a visible image, so you can spot people, vehicles, or equipment by their heat signatures even in darkness, through smoke, or in adverse weather. This makes PAS 25/28 most accurately described as a thermal imager.

Other options describe different functions: a laser range finder measures distance with a laser pulse, a night vision device amplifies ambient light to produce a brighter image, and a communications unit handles data and voice transmissions. The PAS 25/28’s role is about seeing heat signatures, not measuring distance, enhancing low-light visibility, or handling communications.
