摘要
在照相机主动式PSD自动对焦系统中，发射透镜与接收棱镜要求口径大、球差小，价格低、体积小，保证PSD上光斑小而且边缘清晰。本文认为，非球面单片透镜适合该系统。本文导出了非球面透镜的设计方法和计算实例，并给出了AF光学系统总体设计实例。
In initiative PSD(Position Sensitive Device )Auto-Focus system of camera, theprojecting lens and receiving lens must have the large aperture,small aberration,small size,and lower price,to insure the light spot upon the PSD surface small and sharp. According tothis article,the single lens with one aspherical surface can fit this system. The method and anexample for designing the lens with aspherical surface have been arrived. And an example ofthe optical system of this type of Auto-Focus system has been given.
