The second kind angular dispersion and the analysis of characteristics of diffraction grating
衍射光栅的第二类角色散及其特性分析

The first and second kind formulas of angular dispersion, corresponding respectively to the polar angle and azimuthal angle of diffraction grating, are presented based on the generalized grating equation produced on the basis of vector diffraction theory under the condition of conical diffraction mounting; at the same time, by making theoretical and numerical analysis of the condition in which the second kind formula of angular dispersion changes evidently and the corresponding mathematical expression is obtained.
