Abstract
Since the advent of high-speed automatic computing machinery, workers in the field of optical design have been intrigued by the idea of automating the lens design process. Various methods have been proposed and tested. Most of these, in the author’s view, do not allow sufficient control to be exercised over the nature of the design solution. Those which do allow such control appear to be inefficient because of slow convergence to a solution. This paper describes a correction procedure which permits a high degree of control over the nature of the design solution and which has shown a reasonably good rate of convergence in a limited number of tests. The operation of a computer program to carry out the procedure is described, and the results of a typical design problem are presented.
