Wide spectral SWIR star sensor optical system

  • 摘要: 近红外波段测星已成为星敏感器的重点发展方向之一,针对近红外星敏感器使用波段宽的特点,依据消二级光谱理论中可行的两种消二级光谱方法,采用选取相对部分色散系数相同或接近、色散系数相差较大的玻璃组合的方法对近红外星敏感器光学系统进行设计。设计了一组工作波长为900 nm ~1 700 nm,F数为1.5,焦距为150 mm的光学镜头,该镜头在宽光谱范围内实现了二级光谱的校正,在空间频率等于32 lp/mm时各视场MTF均大于0.65,使系统具有良好的像质,能够满足近红外波段的测星要求。
    Abstract: Observing star in shortwave infrared (SWIR) spectrum has been considered as one of the important development directions of star sensor. According to the characteristic of wide waveband used in SWIR star sensor and the two feasible methods for correcting secondary spectrum in theory, an SWIR star sensor optical system with 900 nm~1 700 nm band, F number of 1.5 and the equivalent focal length (EFL) of 150 mm was designed based on the method of selecting the glass combination of the same or nearly relative dispersion coefficient and obviously different dispersion coefficient. Result shows that the secondary spectrum is corrected in broad band, the MTF in full field of view is more than 0.65 at 32 lp/mm.The system has excellent performance that can satisfy the requirement of observing star in near infrared band.
