Design of a Light and Compact Optical System for Star Sensors
轻小型星敏感器光学系统的设计

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.
