大象差系统的优化设计

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。

Optimization Design of the Optical System with large Aberrations

It is effective for the optical system with large aberration to use the MTF as merit function, becanse the MTF value corresponds with the image quality directly, which can be treated as a single evaluation function in the overlap. The MTF can reflect all-sidely and objectively the image quality of optical system. GMTF as merit function is used in the program of automatical lens design. At length an example is giveu to explain the program procedure and the results are lliustrated.
