摘要

以宇宙飞船为载体的航天相机在轨工作过程中

由于受到空间动力学干扰源的作用

飞船、整个光学系统以及光学元件可能会产生振动

并由此引起曝光时间内像点的移动。这些振动必将造成光学系统成像质量的下降。本文探讨了振动过程中像点移动的分析方法--坐标变换法

并利用这种方法计算了航天相机主镜振动时的像点移动。

Abstract

When a space camera which is kept in a spacecraft is working in the space

spacecraft and the optical system of the camera will vibrate because of the existence of space dynamic interruption. So the image point of an object will move during the exposure. For an optical system

the result of motion of the image point will be a degradation of image quality. An analysis method on image point motion due to vibration — coordinates transformation method is discussed in this paper. To illustrate this method

the image motion was calculated due to the primary mirror vibration.
