Analysis of color separation grating of oblique incident wave

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°.
