ABSTRACT:
An optical scene test generator is provided for testing the operation of detector modules designed to be placed in earth orbit. The OSTG includes first and second sources of infrared frequency light sources. The templates may be irradiated to generate images representative of a background scene, such as the earth's surface, and an object moving in relation to the background, such as a missile. Background and object images are thereafter combined and presented upon the surface of an infrared detector element to be tested. Mechanisms are provided for selectively regulating the movement of the background and object images, with respect to each other and jointly with respect to detector modules to be tested.
