摘要
数字微镜器件(DMD)作为红外景象生成器，以其帧频高、空间频率高、灰度等级高、均匀性好等优势，在红外成像制导目标模拟器的研究中受到普遍关注。分析了DMD的工作原理，提出了红外成像制导目标模拟器的组成方案，在实现高模拟温度（大于400 ℃）的同时，灰度等级能达到214。完成了照明系统的光学设计和灰度轮设计。
Abstract
Digital micromirror device (DMD) as an infrared scene generator, which has high frame rate, high spatial frequency, high grayscale, good uniformity and other advantages, is generally concerned in the study of target simulator for infrared imaging guided system. The principle of DMD is analyzed. The composition of target simulator for infrared imaging guided system is proposed. The simulation temperature achieves a high level above 400 ℃, and the grayscale could reach 214. Optical system and gray plate of the lighting system of the target simulator are designed.
