Which component reflects the energy toward the imager assembly?

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

Answer: (A)

In imaging systems, getting the scene energy onto the detector is done by a reflective element that can steer the path of light. The scan mirror sits in the optical path and reflects incoming energy toward the imager assembly, allowing the system to scan across the field of view as it directs energy to the detector. The imager assembly is where energy is collected and converted into signals, not where the energy is redirected. The detector array is the sensing grid inside the imager, and the video indicator simply displays the output. So the component that reflects energy toward the imager is the scan mirror.
