| Abstract: | The stray light properties of the three-mirror optical system used in field bias was analyzed and the basic design principles of the light shade and baffle vanes were presented,then the design of them was discussed.The principles of stray light eliminating and evaluation using computer simulation technology were put forward.Considering that the system had a special rectangular field of view,and the field was off-axis in y direction,a certain demand on the external lens hood was proposed.So box-shaped outer ... |
