摘要
由于红外系统复杂度越来越高,用靶场实验方式测试系统的性能指标已变得十分高昂,甚至无法实现。利用红外图像模拟器来测试红外系统的性能指标是一种经济、实用的办法。本文设计了一款基于DMD的8位灰度红外图像播放器,详细阐述了系统各功能模块的作用,并使用自制的红外热像仪测试了系统的相关性能指标。经测试播放器线性相关度为0.99997,图像非均匀性优于1.7%(含热像仪),图像帧频为252.5 f/s,能够满足大多数红外成像系统仿真与测试的需求。
For the increasing of infrared system’s complexity,it’s a costly,even impossible thing to test various performances of infrared systems in field.Fortunately,there is an economical and practical way to test those indexes by using infrared image simulator.An 8bit gray- scale infrared image player based on DMD is designed,functions of every model are elaborated in detail,and related performance indexes of the system are tested by using thermal infrared imager designed by the lab.According to the tests,its linear correlation is 0.99997,the non- uniformity of image is better than 1.7%（including thermal imager）,and the image frame rate of it is up to 252.5 f /s.It can meet the needs of most simulation and tests for infrared imaging systems.
