Using mat the lab software, in view of the diffraction grating performance's two parameters, namely the angle selectivity and the wave length selectivity, (light grating to with crystal thickness) between relations has drawn the following conclusion with the diffraction grating parameter: (1) works as when diffraction grating thickness fill-out, the diffraction grating choice angle changes is small, the side lobe increases highly; (2), when light grating to enlargement, the diffraction grating choice angle changes is small, the side lobe change is not highly obvious;

Make use of the software of mat lab, aim at light grid function of two three quantity, namely angle selectivity and wave-length selectivity, with light the relation of of the grid parameter(light grid line to and crystal thickness) get if draw a conclusion:(1)The choice Cape of light grid diminishes while pawning everything grid thickness to become big, the side petal highly becomes big;(2)Pawn everything grid line to diminish towards enlarging, light the choice Cape of the grid, side petal height the variety isn't obvious;
