| 摘 要： | 通过对闪耀光栅衍射图样的二维展示,强调了单槽衍射"零级"的意义。首次用三维图演示了特定条件下闪耀光栅仅有一序光谱呈现,入射光波长取闪耀波长时谱线强度有最大值存在,离开闪耀波长时强度逐渐下降;随着入射光波长范围的扩大甚至会出现多序光谱的重叠。

| Abstract: | Diffracted patterns of blazed grating are on a visual display with Mathematica and the meaning of the zero order for single groove diffraction is emphasized.Under given conditions only one order spectrum is presented by three-dimensional picture for the first time when the plane wave is at normal incidence,which has a maximum at the blazed wavelength.In addition,with the expansion of the scope of the incident wavelength even emerge multiple order spectrums. |
