【摘要】 本文根据三级像差理论,讨论了满足系统为会聚光路、系统遮拦比|α|<1两个条件的两镜系统,分析了以消球差S₁=0为初始条件,同时校正其余像差系数S_II,S_III的系统。对在不同非球面系数条件下,主镜、副镜的面形以及比较半径R₁,R₂随遮拦比α和放大率β的变化作了分析,并总结了现有已命名的经典系统。更多还原

【Abstract】 The two-mirror systems which are convergent and comply with |a| < 1 are discussed based on the third-order aberration theory. A general analysis on zero-coma system and zero-astigmatism system with the initial condition of zero-spherical aberration are figured out.The variety of the vertex radius of curvature R1, R2 and surface figure of primary mirror and secondary mirror with obstruction ratio a and amplification β with different aspheric coefficient are analysed. The classic systems which consisted of two mirrors are summarized.更多还原
