光束斜入射的分频光栅衍射行为研究
Analysis of color separation grating of oblique incident wave
-
摘要: 用标量理论和矢量理论分析了光束斜入射时分频光栅的衍射行为，分频光栅在光束斜入射时的分频效果，以及入射角度的有效范围。计算结果表明，并非严格的正入射才能保证分频光栅的分频效果，在光束入射角度小于5°时仍然可以满足ICF系统的要求。Abstract: The scalar method and vector method were applied in the analysis of color seperation grating of oblique incident wave. This paper checks the effect of color seperation grating when the angle of incident wave changes and tries to give the region of incident angle when the color seperation grating has good effect. The results verify that the color seperation grating can be efficient and can satisfy the ICF system when the angle of indident wave is less than 5°.
