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.

An optical scene test generator (OSTG) useful in testing the operation of detector modules designed to be placed in earth orbit, the module having a first surface upon which an image may be formed, the OSTG comprising: a first source of IR frequency light; a first template having at least one aperture formed therein through which IR frequency light from the first source of IR frequency light may be transmitted to generate a first IR frequency light signal representative of the earth\s surface; a second source of IR frequency light; a second template having at least one aperture formed therein through which IR frequency light from the second source of IR frequency light may be transmitted to generate a second IR frequency light signal representative of a target; an optical image combiner for receiving and combining the first and second IR frequency light signals, and for directing the combined first and second IR frequency light signals to the detector module to be tested; and template positioning apparatus connected to each of said first and second templates for positioning each of said first and second templates relative to one another and relative to said detector modules such that the independent motions of a target and background may be simulated.
