摘要
讨论了以长焦距、宽视场光学系统为应用背景的多视场离轴全反射式光学系统。全反射式光学系统进行离轴使用,可以实现无中心遮拦,能量利用率高。在离轴全反射式光学系统中通过移动或旋转反射镜组可得到多视场离轴全反射式光学系统。分析了多视场离轴全反射式光学系统的设计基础、设计方法及特点,并给出了双视场离轴全反射式光学系统和三视场离轴全反射式光学系统的设计结果。
The off-axis all-reflective optical system with multiple fields of views is discussed.The all-reflective optical system with off-axis elements can＇t obstruct center energy and it can make full use of the whole aperture＇s energy.The off-axis all-reflective optical system with multiple fields of views is obtained by moving or pivoting the mirrors of the all-reflective optical system.At the same time,the principle,techniques,and difficulties of the off-axis all-reflective optical system are analyzed.The design results and image evaluation of the off-axis optical system consisted of three mirrors with two field of views and the off-axis optical system consisted of four mirrors with three field of views are presented respectively.
