摘要

提出了一个大相对孔径、大视场轻小型CCD星敏感器光学系统设计方案

该星敏感器焦距为22.5 mm

数为1.2

谱段范围470~750 nm

视场角25°。采用双高斯基本型后加一片近乎等晕的正透镜

获得了较大的相对孔径

同时选择高折射率玻璃材料增大视场并降低轴上及轴外光束入射角

高折射率玻璃材料亦能降低高级像差且使系统总长缩短。像质分析表明

此设计方案能够满足使用要求

光学系统总长仅为46.51 mm

满足实际工程轻量化需求。

Abstract

Star tracker composing of optical system

photoelectric receiver and image processing element is a key equipment of satellites for star position. In this paper

we present a optical system of light CCD star tracker with wide filed and large aperture in a focal length of 25 mm

-number of 1.2

a working wavelength range of 470~750 nm and a view angle of 25 degrees. The optical system is composed of a double-Gauss lens and a piece of positive lens

considering the large

number. In order to decrease the input angles of the axial and off-axial light bundle

the glass with high refractive index is used to produce smaller high-order aberrations and shorten the total length of the system. The imaging analysis results show that the design is a feasible scheme

and the total system length is only 46.51 mm.
