An Algorithm for Obtaining a Spot Diagram Based on Buchdahl Aberration Coefficients

An algorithm for obtaining spot diagrams of an optical system by using Buchdahl aberration coefficients is presented in this paper. The relevant calculating formulae and computing examples are also given,the relation beteween the merit function and optical transfer function (OTF) is discussed. The theoretical analysis and practical computating show that the algorithm can give out the spot diagrams approxmately and thus decreases computation time greatly. It is fit to be used as merit fuction in optical optimazition design by a personal computer.
