摘　　要：由于变焦系统的凸轮曲线对变焦过程中像面的稳定、操作的灵活性都有重要影响,因此变焦曲线的优化设计有着重要的意义。首次采用遗传算法对机械补偿类型的变焦曲线进行了优化设计,并给出了实例。这样得到的曲线比传统的让变倍组作线性移动得到的曲线要明显平滑,证明了遗传算法用于变焦曲线优化设计的可行性和有效性。The optimization design of the cam curve is very important in the design of a zoom system because it will eventually affect the stability of image surface and flexibility during zoom operation. Theory of using the genetic algorithm (GA) in the optimization of the cam curve of mechanically compensated zoom lens is proposed. Program is made up and the design example is given. The result of the example shows that the cam curve designed with the method of genetic algorithm is much smoother and better than those with the traditional ways.
