摘要
定义了调制传递函数相似度作为优化波前编码系统的评价函数,并在光学设计过程中通过引入数学软件实现了波前编码系统的快速优化。在优化过程中,通过引入数学软件与光学设计软件的动态数据交换接口实现了优化函数的快速计算和高速数据交换,并通过采用遗传算法加快了评价函数收敛速度。经过优化系统调制传递函数相似度由原来的0.0187降为0.0119,且调制传递函数幅值均高于0.18,处于设定的范围内。研究结果表明动态数据交换和外部程序的引入可以进一步提高具有特殊性质的非常规光学系统优化效率。
The invariance of modulation transfer function （MTF invariance） is defined to be the evaluating criterion of the wavefront coding system. The rapid optimization of wavefront coding system based on the MTF invariance is proposed by means of introducing the mathematical program to normal optical design process. The interface called dynamic data exchange （DDE） interface, between mathematical program and optical design program is applied to realize the fast data exchanging and merit function calculating. The MTF invariance of the optimized system decreases to 0. 0119, compared with 0. 0187 of the original system. Results show that the optimization of special optical systems can be executed more conveniently and fleetly with the help of external program and dynamic data exchange.
