| 摘 要： | 由于变焦系统凸轮曲线的的质量直接影响像质,因此从实际应用出发，以变焦方程和动态光学原理为依据，结合实际工作中需要设计的变焦镜头，通过对变焦系统高斯计算的过程进行分析，指出影响凸轮曲线的主要因素为变倍组和补偿组的焦距以及二者的间隔。针对3个参量之间的对应关系进行讨论，提出了优化凸轮曲线的方法。

| Abstract: | Based on the zoom equation, the dynamic optics principle and the process analysis of the Gauss calculation for zoom systems, it is pointed out that the primary factors which influence the cam curve are the focal length of the zoom lens group and compensating lens group, and the distance between them. The relationships between the three parameters were discussed. The method to optimize the cam curve is proposed. |
