潜望镜照相窗口光学系统二级光谱校正分析

Correction Analysis of Secondary Spectrum Optical System in Periscope Photographic Window

潜艇潜望镜光学系统的二级光谱非常大,严重影响潜望镜照相窗口照片的清晰度和分辨率.根据二级光谱像差理论,将多光谱CVD硫化锌光学材料应用于潜望镜照相窗口光学系统.采用光学设计软件ZEMAX进行优化设计,结果表明这种材料在潜望镜照相窗口光学系统中具有良好的消像差作用,成像质量优良,能满足较高的使用要求.最后进行了环境变化对光学系统的影响分析,确定了该光学系统的环境自适应区间.

Secondary spectrum of submarine periscope optical system is very large, which can influence the clarity and distinguishability of periscope photographic window picture. According to the theory of secondary spectrum aberration, multispectral CVD sulfide zinc optical materials is applied to a periscope photographic window optical system. To make optimized design by using ZEMAX optical design software, the results show that this material, which used in the window of periscope photography optical system has good aberration effect and excellent image quality, it could meet higher requirements. Finally, the influence of the environ- mental change on the optical system is analyzed; and the environmental adaptive optical system is identified.
