摘要
在光学反射矢量理论的基础上,分析了二维指向镜的定域扫描方式的非线性扫描特性,给出了指向镜二维扫描的轨迹及像旋角的计算公式,提出了对扫描轨迹进行非线性校正的方法.在不进行消旋处理的情况下,将二维指向镜的定域扫描方式直接应用于点源探测系统如红外系统中.
Based on the vector theory of optical reflection, nonlinear scanning traces charactenstics ot the two-dimensional pointing mirror in the scanning mode in the given area is analyzed. The expression of scanning trace and image rotation angle and the method of non-linear scanning trace modification are given. Without eliminating the image rotation, this mode can be used in point ohiect detecting system, such as IR detecting system.
