Abstract: To improve the application question of the timing synchronization, high frame rate display and optical match caused by infrared scene simulation equipment based on DMD in the hardware-in-the-loop simulation test, a novel infrared scene simulation equipment based on DMD which can match application with several kinds of common infrared staring imaging system was designed and constructed. Firstly, the scheme of synchronization delay driving and the scheme of display control were proposed. The synchronization signal processing circuit and the driving circuit were designed and developed, the timing synchronization and high frame rate display were realized. Then, according to parameters of optical system of several kinds of common infrared staring imaging system which will be tested, the lighting optical system and the projection optical system were designed, developed and simulated, optical match with several kinds of common infrared staring imaging system was realized. Test results indicate that the equipment can realize timing synchronization and optical match between the equipment and several kinds of common infrared imaging system, the frame rate of the simulation image is 300 Hz, the maximum simulation temperature of the simulation image is 160℃, the minimum simulation temperature of the simulation image is 0.03℃, the maximum contrast of the simulation image is 0.7, the nonuniformity of the simulation image is 1%, the equipment play a key role in a large number of hardware-in-the-loop simulation tests.
