Paper Abstract

Basic principles of stray radiation suppression are employed in a FORTRAN computer pro-gram that assists in the design of well-baffled axially symmetric optical systems. Called GOSBOP (General Optical System Baffle Optimization Program) , this program can design the baffle structure of a typical system according to the user's specifications in less than a second on a CYBER 175 computer. The program can also be used in conjunction with a new version of the first APART (Arizona's Paraxial Analysis of Radiation Transfer) subprogram to design and evaluate a baffled optical system in a single computer run with a minimal amount of input. The programs enable the user to identify and eliminate troublesome single diffuse scattering paths so that a preliminary design can be optimized in terms of both optical performance and stray radiation suppression in only a few successive computer runs. As an example, the technique is applied to optimizing the baffle structure of a typical Cassegrain telescope such that the stray radiation reaching the image plane is reduced by up to three orders of magnitude. The stray radiation rejection of the final design compares favorably with relatively more complicated designs.
