基于数字微镜器件(DMD)的红外场景仿真系统中图像显示是采用灰度调制技术实现的。介绍了DMD灰度调制技术的原理。分析了在探测器帧频不变的情况下,调整DMD显示帧频,图像灰度调制与探测器帧频之间的关系,得出如果DMD显示帧频与探测器帧频满足一定关系,不外接同步信号探测器也可以得到完整的图像,并通过实验进行了验证。

In the dynamic infrared scene simulation system based on digital micro-mirror device(DMD), gray modulation technique is adopted to realize image display. The principle of gray modulation technology of DMD is introduced. With the premise of the invariant detector frame frequency, with the analysis of the relationship between image gray modulation and detector frame frequency, experiment verifies that if DMD display frame frequency and detector frame frequency satisfy a certain relation, the detector also can get the unbroken image without external synchronization signal.
