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。
This paper mainly introduces a design method of mechanical compensation type three anti-zoom system based on Seidel aberration theory. The advantage of this method is that some initial structural parameters satisfying the requirements can be obtained by constrained optimization of the primary aberration equations. The design examples show the feasibility of this method. At the same time, the limitation of the above method and the necessity of design of omni-reflection system are pointed out. And a new theory of design is discussed. The method of eliminating the system obstruction and correcting the aberration is given.
