摘要
介绍了星敏感器的工作原理,对光学系统的指标进行详细的分析,给出光学系统的设计结果和评价设计得到的镜头焦距22.7mm,相对孔径1∶1.4,视场角17.1°×17.1°(圆视场角24°),而长度仅45.3mm由七个球面透镜组成,光阑放在第二。
The principle and the performance index of compact optical system for star sensorsits are introduced and analyzed. An optical system used for star sensors is reported. It is composed of seven spherical lenses, and the stop is between the second and third lens. Its focal length, relative aperture, and field of view are 22.7 mm, 1∶1.4, and 17.1°×17.1°(circular field of view is 24°) respectively.And its total length is only 45.3mm.
