摘要
本文讨论了变焦系统优化过程中有关渐晕系数处理的问题,指出在每次迭代前,为计算实际通过该系统成象光线的象差,预先确定各视场的渐晕系数是必要的。文章同时给出了计算渐晕系数的新方法。实际优化结果表明:运用该理论进行自动设计,可以充分发挥成象系统的潜力。
In this paper, the problem on how to deal with the vignetting coefficients in the optimization design of zoom lenses has been discussed. The authors consider that before each iteration process, it is necessary for the optical system to calculate the vignetting coefficients of various view fields at every focal length for acquiring those genuine aberrations. Meanwhile a new method to compute the vignetting coefficients has been given. The result of examples shows it can bring the potential of the optical system into full play by applying this method.
