基于稳像理论的空间光学遥感像移补偿的分析与计算

动态光学是研究光学系统及元件动态成像特性的一门学科。稳像系统是动态光学系统的重要组成部分。稳像系统是为了维持图像的稳定、清晰，要求光学组元件按规定的要求做相对运动，从而实现图像的最终稳定、清晰。空间遥感成像的分析对于遥感器的运用至关重要。基于稳像理论——动态光学理论，进行了空间遥感器的成像面像移分析，分析结果与采用齐次坐标变换方法所得结论一致，不但证明通过齐次坐标变换方法得出的结果是正确的，而且说明采用动态光学的稳像理论解决以上问题物理概念更清楚，计算简便。同时对于类似的运动光学系统，稳像理论也具有很好的适用性。

The Application of the Theory About Image Stabilization in Calculating Image Motion on Space Remote Sensor

Dynamic optics is a subject, which studies dynamic imaging characteristics of optical system and optical components in dynamic status. Image stabilizing system is an important part of dynamic optical system. The aim of movement between optical components of optical system is to reach some goal, for example, goal of circumrotation of scanners of the scanning and tracking system is to capture and track target. In an imaging stabilizing system, when the optical instrument installed on some carrier, the motion of carrier causes the image motion, so causes the image blur, in order to keep the stabilization and clarity of picture, the optical components must have some relative motion. To apply a spacial remote sensor, the remote imaging analysis is the key problem. Based on image stabilizing theorydynamic optical theory, the analysis of image motion of spacial remote sensor is given. The result shows the concise concept and simple expression of this method, which is consistent with uniform coordinate transform method. Similarly, for the similar moving optical systems, the theory of image stabilization is also applicable.
