Abstract

Pointing errors in telescopes carried by space vehicles can be compensated by servo-control of the secondary mirror. This introduces some aberrations in the stabilized image, the magnitude of which depends on the asphericity of the telescope mirrors. A configuration is presented in which the centered image of an off-axis object point is free from coma. The required aspheric corrections and the residual aberrations are calculated. Also included is a summary of the third order aberration constants for some well-known centered cassegrain-type telescopes.

摘要

航天器搭载的望远镜中的指向误差可通过副镜的伺服控制来补偿。这会在稳定图像中引入一些像差，其大小取决于望远镜镜面的非球面性。本文提出了一种配置，其中离轴物点的中心图像没有彗差。计算了所需的非球面校正和残余像差。还包括一些著名的中心卡塞格伦式望远镜的三阶像差常数总结。
