GOLD光学设计软件及其技术性能

Technical Features of GOLD──Software for General Optical Lens Design

利用物象空间正则归一化坐标理论，研制出光学系统自动设计大型软件包（ＧＯＬＤ）．其功能包括光路追述，象差分析，点列图、点扩散函数、光学传递函数等象质指标的计算，两次反射鬼象和红外扫描成象系统中的冷反射对系统影响的模拟和控制，阻尼最小二乘法结构优化等等．ＧＯＬＤ软件适用于各种非对称、非常规复杂光学系统的设计分析，经实践应用得到满意的效果．

A software package for automatic optical design is developed using the theory of canonical coordinates At present, its features include lay-tracing, aberration analysis, calculation of image criteria such as spot diagram, point spread function and optical transfer function, simulation and control of ghost hages and Narcissus effects (for amming infrated systems), damped-least-squares optimization, etc. The software is capable of handling all kinds of general optical systems, i. e., systems without rotational symmetry and/or with unconventional optical elements. Satisfactory results are achieved in practical applications.
