A new method of baffle design

<p> Nowadays, as the development of the level of the land observation technology constantly improved, the demanded of the image quality are increasing rise. There are so many possibility factors which may influences of the image quality, especially in the inferred optical system, the main reason of them is stray light. The baffle is the main element in the observe system which can inhibit the stray lights that comes from out side of the system. The paper will show you an new idea in baffle design, we put the block aura in an angle which is not 90 degree in conventional. The design can keeps the stray lights out of the system or been greatly absorbed on the condition of low absorption rate of the baffle. We will show you the evidences of calculation, and gave you the basis of the design.</p
