Design and test of DMD dynamic IR scene simulator

Infrared scene simulator is necessary in hardware-in-the-loop simulation for infrared guidance weapons. Infrared scene simulation software was developed on the basis of Vega 3.7, a high performance visual simulation development platform, and its SensorVision module. Real-time infrared images were generated to drive Micromirror Array Projector System (MAPS) based on the Texas Instruments Digital Micromirror Device (DMD). The infrared imaging guidance simulation system structure, image generation software and infrared scene projector were studied and designed respectively. Test of the projector was introduced, including analysis of resolution, contrast ratio, ununiformity, geometrical aberrance and min discriminability. This simulator system has been applied to the research on the seeker of certain type of infrared missile, and ideal results have been obtained.
