A Novel Design of Off-axis Three-mirror Reflective Optical System
一种新型离轴三反式光学系统的设计

The optical system with compact structure, wide field of view and long focal length is discussed and an off-axis three-mirror reflective optical system with 1000 mm focal length ,aperture of f/4 and 3°field of view is designed on the basis of geometry optical theory. Moreover, the infection of system and aberration made by optimize method and parameter is discussed.
