| 摘 要： | 在CBERS-1卫星红外多光谱扫描仪中,校正器采用了两个反射镜相互平行的方案,当校正器转角很小时,校正器的补偿角速度可以近似认为是线性的。文章分析计算了当校正器的两个反射镜相互不平行时,校正器的旋转所产生的误差,通过分析计算得出,当校正器转角较小及光学系统的像差要求不很高时,校正器的两个反射镜相互不平行是可以使用的。

| Abstract: | Scan Line Corrector(SLC) is composed of two parallel mirrors in IRMSS for CBERS - 1 Satellite. When the rotation angle of the SLC is very small,it can be considered that the compensative angular speed of the SLC is linear. In this paper, the error is calculated that was brought by rotation of the SLC in which two mirrors are unparalleled. It is present that the SLC with two unparalleled mirrors can be used when the rotating angle of the SLC is very small and the requirement of the optical system aberration isn t very high. |
