摘要
本文给出了一种类似于施密特非球面校正板作用的梯度折射率介质平板,这种介质是一种弱径向梯度折射率介质。
In this paper is described a gradient index media plate. The media plate has some properties similar to the Schmidt aspherical corrective plate. In the cata-dioptiric system. Duncan T. Moore has studied a axial gradient index corrective plate and gave a better result. This plate, in fact, is a zero power plate with two spherical surfaces of different radius of curvature. But my plate is designed with a shallow radial gradient index media, and it is a plate with a parallel plane.?The spherical aberration of the gradient index corrector with parallel plane will eliminate the spherical aberration of the spherical primary mirror in the catadiop-tiric system. In this paper is analyzed the aberrational correction. In the conventional optical systems, this gradient index plate is used to provide the precorrec-tional quatity of the spherical aberration of the optical lens systems. The refractive index in such a media in the lens systems is given in the same way.
