Which component converts the light into video signals representing the infrared energy?

• A. Camera Assembly
• B. Video Indicator
• C. Imager Assembly
• D. Detector Array

Answer: (A)

In infrared imaging, the step that turns captured infrared energy into a video signal is handled by the camera assembly. The detector array is the sensing element that converts IR photons into an electrical signal, but producing a usable video signal requires the camera assembly’s readout, amplification, and video-output electronics. The camera assembly integrates the detector with these electronics to produce a video-format signal that can be displayed. The imager assembly may include optics and the sensor, but the actual conversion to video signals is performed by the camera assembly. The video indicator is simply a display and does not generate the video signal itself.
