Paper Abstract

Large numbers of rays must be traced to obtain an accurate assessment of the sensitivity of a lens to certain manufacturing perturbations, such as optical surface irregularity and aspheric departures. To properly assess image quality changes, the perturbed lens must be re-focussed. This paper deals with the development and testing of an algorithm to automatically determine the focus of aberrated images with a computer.
