大象差光学系统以传递函数MTF作为评价函数进行自动设计为宜。因为MTF与系统质量直接对应,迭代中可处理为单一的评价函数,能全面而客观地反映光学系统的成像质量,本文阐述了一个以几何传递函数GMTF为评价函数的光学自动设计程序中几个有关问题的处理方法,并给出了具体实例说明程序的应用过程和效果。
The aberration optical system of elephant is designed automatically by the transfer function MTF as the evaluation function. Because MTF directly corresponds to the quality of the system and can be treated as a single evaluation function in iteration, it can comprehensively and objectively reflect the imaging quality of the optical system. In this paper, we describe a few of the optical automatic design programs that use the geometric transfer function GMTF as the evaluation function The way to deal with the problem, and gives a concrete example to illustrate the application process and effect of the program.
