开发了一种几何理论，用于具有可变线距和弯曲凹槽的球面凹面衍射光栅，并且可以用现有技术生产。确定该光栅的像差系数。将这些系数与全息光栅的相应系数以及 CODE V 多项式系数进行比较，可以更清楚地了解机械刻划凹面光栅和全息记录凹面光栅之间的相似性和差异，并允许使用标准计算机程序优化这些光栅。
A geometric theory is developed for a spherical concave diffraction grating that has variable line spacing and curved grooves and can be produced with existing technology. The aberration coefficients of this grating are determined. A comparison of these coefficients with the corresponding coefficients of holographic gratings and with CODE V polynomial coefficients gives a clearer understanding of the similarity and difference between mechanically ruled and holographically recorded concave gratings and allows the optimization of these gratings with standard computer programs.
