光栅衍射条纹次极大强度研究

Study of grating diffraction stripe secondary maximum

算出三缝到八缝光栅的各次极大衍射条纹次极大强度。发现单缝衍射因子对各次极大均有调制作用 ,但其单缝衍射强度的调制系数却不相同。

By calculating grating diffraction stripe secondary maximum form 3-slot to 8-slot of grating,I find single-slot grating factor will modulate secondary maximum,but the coefficient of modulate function is different.
