Abstract: A sensor test system is disclosed for testing the operation of infrared detector modules designed to be placed in earth orbit. The system includes an optical scene test generator (OSTG) for generating a scene representative of the earth's surface as seen from a satellites, and an object moving in relation to the earth's surface. Sensor chamber is disposed adjacent the OSTG for storing a detector module to be tested. Detector module is efficient within the sensor chamber to expose detector elements to the optical scene generated by the OSTG.

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.

Abstract: A sensor chamber is disclosed for testing the operation of detector modules designed to be placed in earth orbit. The sensor chamber includes a chamber housing and a vacuum pump for evacuating the sensor chamber housing to vacuum conditions representative of a space environment. An infrared detector module is disposable within the sensor chamber, the module being operative to receive an infrared frequency signal and generate an output signal in response thereto. A window is formed within the sensor chamber housing, adjacent the detector module, to facilitate communication of infrared frequency signals to the detector module. A detector servo mechanism is provided for regulating the orientation of the detector module within the sensor chamber housing. The detector servo being operative to effect movement of the detector module with respect to the infrared frequency signal.

Abstract: A real time color display system for converting input data to color drive signals is disclosed, which permits individual color intensity signals corresponding with individual data input signals to be selectively varied. The display system comprises an interface circuit connectable to an external data source and first connector terminals of a programmable device. A memory access circuit is connectable to the data source and second connector terminals of the programmable device. The memory access circuit comprises circuitry for generating address information and is adapted to transfer data and corresponding address information to the second connector terminals of the programmable device. A video circuit is also connected to the programmable device and to the data source. The video circuit comprises color registers for storing color drive signals, color coding circuitry for loading the color registers and color translating circuitry for communicating data to the color registers.
