| Abstract: | Optical systems which have stringent requirements on stray light levels,such as spaceborne optical system,often need light shade. In this paper,an optimum design method for the light shade of spaceborne optical system is discussed.Some basic design principles for stray light control of light shade and vane structure are presented.The location of vanes and the structurc of two stage light shade are calculated by computer,and one stage and two stage light shade are compared. |
