导出了单个光栅的十六个波前像差系数的表达式。对于平面对称光栅系统，这给出了四阶波像差。来自每个反射镜和光栅的贡献可以相加以给出最终图像中的像差。通过定义相对于衍射参考表面的波前像差，克服了中间衍射图像遇到的问题。存在一个描述物点从对称平面的位移的场变量。孔径光阑可以放置在系统的任何位置，并给出了移动该位置所产生的像差变化的方程。
Expressions are derived for the sixteen wave front aberration coefficients of a single grating. These give the wave aberrations to the fourth order for a plane symmetric grating system. The contributions from each mirror and grating can be added to give the aberrations in the final image. Problems encountered with intermediate astigmatic images are overcome by defining the wave front aberration with respect to an astigmatic reference surface. There is one field variable describing displacement of the object point from the symmetry plane. The aperture stop may be placed anywhere in the system, and equations are given for the aberration changes produced by shifting this position.
