Application of differential ray tracing equations in automatic design
Using the DET equations proposed by Feder on microcomputer, we have proved that in evaluating a differential matrix the differential method is better than the difference method. It s advantages include high precision, high computing speed in the case of several variables and good convergence ability in automatic design programs.
