Abstract
A light source is injected into an optical path of a camera to provide a controlled background to insure optimum uniformity of performance of the camera. An optical system, camera, image background measurement system, source intensity control, and light source comprise a closed loop control around the light source to control an operating point of the camera. Intensity of the light source is decreased as intensity of a background flux is increased.
