摘要
航空遥感器扫描反射镜按照给定的速度旋转,补偿飞行器运动以及姿态变化引起的像移,为此需要确定补偿后反射镜的大小、航空遥感器窗口的位置与大小。运用光学反射矢量的基本理论,给出扫描反射镜的反作用矩阵,补偿后光线矢量间的关系;通过推导建立扫描反射镜转轴位置与反射镜大小、窗口位置及大小的理论计算公式;以实际遥感器的的工作参数为条件对结果进行计算和分析。实例计算表明理论公式计算简便,不仅在遥感器设计时用于计算反射镜与窗口的尺寸及位置,还可作为具有相似反射镜结构的其他系统的计算依据与基础。
In order to compensate the image motion created by the movement and gesture of aircraft, scanning mirror of aerial sensors is designed to rotate at a given velocity. A practical design about the position and dimensions of the scanning mirror and the window is given in this paper. Based on the vector theory of optical reflection, the scanning mirror＇s reflection matrix and the relation between the ray vectors are given. The relation between window＇s characters and the position of scanning mirror＇s rotation center is also given. The results are analyzed and studied. It shows that the derived formulations can be used to the developed aerial sensor and other similar systems.
