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.
针对一种具有可变线间距和弯曲槽且可采用现有技术制造的球面凹面衍射光栅，开发了一种几何理论。确定了该光栅的像差系数。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，能更清楚地了解机械刻划凹面光栅与全息记录凹面光栅之间的异同，并允许使用标准计算机程序对这些光栅进行优化。
