摘要
主要介绍了一种基于赛德尔像差理论的机械补偿型三反变焦系统的设计方法。这种方法的优点在于,通过对初级像差方程组进行约束优化,可以得到满足要求的部分初始结构参数,设计实例的结果表明了这种方法的可行性。同时指出了上述方法的局限性以及进行无遮拦反射变焦系统设计的必要性,并做了新的设计理论探讨,给出了去除系统遮拦同时矫正像差的方法。
Abstract
A method based on the 3rd-order aberration theory is described for the design of mechanically compensated reflective zoom systems with 3 mirrors. By constrained optimization of a set of Seidel aberration coefficient functions, the initial construction parameters of the optical system can be achieved, and the design results prove the feasibility of this method. The limitation of the above method and the necessity of the design of reflective systems without obscuration are also pointed out. A new design theory is explored which could eliminate obscuration and correct aberrations at the same time.
