Which component is described as the device that converts infrared energy into a visible light image?

• A. Infrared Detection System
• B. Collimator Assembly
• C. Detector Array
• D. Video Indicator

Answer: (A)

Infrared energy from a scene is captured by the detectors in an infrared detection system. These detectors convert the IR photons into electrical signals, which are then processed to form an image that is displayed on a video indicator. The whole chain—detection, signal processing, and display—produces the visible image. The detector array by itself only senses and converts energy to a signal; it doesn’t generate the final visible image. The video indicator is simply the screen that shows the image, not the device that creates it. The collimator shapes the optical path but doesn’t convert IR energy into a visible image.
