摘要
The imaging properties of aspherical diffraction gratings that have curved and variable spacing grooves are investigated theoretically for simple rotational mountings. Methods for eliminating aberrations are examined by clarifying the relations of both the shape of the grating surface and the pattern of the grooves to the individual aberrations, such as astigmatism, coma, and curvature. Application of the methods to the Seya-Namioka are described.
