摘要
针对变焦距物镜设计中高斯光学参数求解的难点,利用几何光学和乘子罚函数法对单变倍组与单补偿组、双组连动和多组元全动型等变焦距系统的高斯光学参数求解进行了研究,给出了系统高斯光学参数的求解方法.给出的计算方法不仅可用于求解多组元全动型系统的高斯光学参数,对简单系统的变焦参数求解也有效.
Based on geometrical optics and dampedleastsquares optimization and applying penalty functions, methods of determining the Gaussian parameters are studied for different types of zoom lenses, including those with one zooming group and one compensating group, with two zooming groups moving in connection, and with multiple moving groups. The method proposed can not only be used for complex zoom systems with multiple moving groups, but also for simpler types of zoom lenses.
