摘要
为了解决非球面光路计算复杂的问题,在对现有光路计算方法进行分析的基础上,给出了基于辅助曲面的步进-二分法。对实际光学系统的光路计算表明,该方法不仅计算速度快,而且可消除光路计算过程中可能出现的光线"溢出"和"伪交点"现象。也适用于球面镜和平面镜的光路计算。
To solve the problems of complex calculation on the aspheric optical system,a stepping-dichotomy based—auxiliary surface was presented on the basis of analyzed existing light path calculation methods.Experimental results of practical optical systems show that this method not only has fast calculating speed,but also eliminates effectively light ray "overflow" and "pseudo cross point" that possibly arise in computing.It also applies to the light path calculation of spherical lens and plane mirror directly.
