摘要
根据机载飞行头盔特点及人机工程要求,设计了护目镜型头盔显示器光学系统.分析了该光学系统的光学性能和畸变特点,研究了该光学系统畸变的算法软件校正方法,设计了预畸变校正算法软件,并对护目镜型头盔显示器光学系统进行了畸变校正.结果显示:校正后光学系统具有很高的成像质量,空间频率为50lp/mm时,全视场调制传递函数接近0.2;同时畸变小于0.5%,系统满足机载护目镜型头盔显示器性能指标要求.
An optical system for airborne Helmet Visor Display（HVD） is designed according to characteristics of the airborne helmet and requirements of man-machine engineering. The optical performance and distortion model are analyzed,and the distortion correction algorithm and software are presented to reduce the distortion of the designed optical system. Experimental results show that after correcting the distortion for the designed optical system,a high imaging quality is achieved,the MTF approaches 0.2 at the spatial frequency of 50lp/mm,and the full field of view distortion is less than 0.5%.The results meet the demands of airborne Helmet Visor Display（HVD）.
