摘要
为了寻找求解多组元全动型变焦系统更加简单而有效的方法,采用程序法的形式,通过给定初始参数(各组元倍率、间隔),对目标系统进行初始数据计算;然后通过给定其限制条件(正切差、变焦曲线曲率、视场角和系统总长)作为控制指令对数据进行优化;最终给出满足条件的光焦度分配,并计算出系统各组元数据参数。为了验证该方法的可行性,以四组元全动型变焦物镜为例,计算出了满足条件的系统参数,通过程序给出的初始数据在光学设计软件Zemax上完成光学系统仿真设计。将程序给出的光焦度分配与Zemax给出的焦距结果进行了对比,结果表明两者数据非常接近,从而证实了该方法的可行性。
In order to find a more simple and effective method to solve the formula of the all lens elements movable zoom lens, in this article, the computer program is adopted. With the given initial parameters （magnification of all elements- distance）, the initial data are computed for the target optical system and the system data are optimized using the restrictive conditions （two tangent data difference - curvature of the zoom curve and total length of the system） as the command. Then the optical-power distribution which satisfies the condition is given out and the data of the optical system are computed. In order to test the practivity of this method, a four movable components zoom lens is designed as an example by using the initial data, given by the computer program, on the optical design software. Comparing the data of the optical power distribution with the Zemax simulation results, we find they agree well with each other, which nroves the nracticality of the method
