宽光谱大视场航空相机模拟器光学系统设计

摘要

The optical design of aerial camera simulation system is introduced,the properties of the near -infrared glassl were discussed . A design example of optical system, with spectral region of 0. 4～1. 0 μm, focus of 2000 mm, full field view angle of Wand relative aperture of 1:10, is given on the basis of the optimization of optical design software ZEMAX. Evaluations have shown that the image quality is close to the diffraction limit.%分析了近红外波段玻璃的材料特性,介绍了一种用于航空相机模拟器的光学系统设计方法,用ZEMAX作了优化设计.给出了光学系统焦距为2 000 mm,相对孔径为1/10,视场角为±5°,光谱范围为0.4～1.0μm的光学系统的设计实例.从像质评定可以看出,系统的质量基本上达到了衍射极限.
