摘　　要：提出了一种二维大视场红外动态图像投影系统的结构设计。采用一个X_Z平移台和一个二维摆镜实现了红外图像的投影。结果是,在垂直和水平方向上的视场角可达到±30°,系统的瞬时空间分辨率为5对线/mm,瞬时投射视场角为3.3°,角精度在1′以下,动态响应特性为2.4Hz。A structure of projection system is presented for planar dynamic infrared image with large field of view. A X-Z axis platform and a planar rotary stage were adopted, which could achieve infrared image projection. The maximum angle of view is ±30°at the direction of horizontal or vertical, instantaneous space resolution is 5 lp/mm , instantaneous project angle of view is 3.3°, the precision of angle is below l＇, and dynamic responding is 2.4Hz.
