Paper Abstract

A computer program has been developed to analytically describe the first and third order properties of systems with large tilts and decentrations. The program describes the imagery through analytic formulae, in both the pupil and field variables, rather than by interpretation of ray trace data at sample points in the field. The first order properties of both the image and the pupil are described in terms of tilt, decentration, magnification, keystone distortion, and anamorphic distortion parameters. In computing these parameters, it is important to take into account the transferred components of the parameters, which are due to the first-order properties of the previous surfaces. The third order properties are computed by representing the surface aberration contributions as vector fields and summing them vectorially. The third order properties are described in terms of a coma field with a node displaced from the center of the image, a binodal astigmatism field, a trinodal distortion field, and a focal surface that is curved and displaced from the Gaussian image in both the transverse and longitudinal directions. The program is applied to several systems, and the results are compared to ray trace data. The interaction between large first order aberrations of intermediate images and pupils, and the third order properties of the image is discussed. Applications of the vector aberration field technique toward an automated design procedure are considered.
