英文摘要 | During process of satellite attitude control, the star sensor provides accurate attitude information for the entire control system, and then ensures the precision of following control operations and the stabilization of flight track. To these satellites in the medium and high Earth orbit, the transmittance of entire system will rapidly attenuate after suffering a long time irradiation of space particles, which leads to the inefficacy of total star sensor and inability of providing accurate attitude information for the satellite control system. This paper presents an optical system of long-life star sensor, with optical characteristics that focal length is 49.7mm, relative aperture is 1/1.18, circular field of view is 14.14°, and the spectral range is 0.51/20.8μm. That can meet the requirement of work time at least eight years in space. The optical system is designed by all spherical mirrors with an compact structure which is just composed by six lenses. the first lens of optical system is fused quartz, the other are just made of two different optical glasses. There are some advantages that its energy is more concentrated because of small dispersed spot and low chromatic aberration, it is to be the benefit of overall debugging with better adaptability to the environmental temperature, and it has the function of optical filtering that the transmittance is higher in the work range of spectrum and is lower out the work range of spectrum, which is benefit to eliminate the stray lights. © 2019 SPIE. |
