摘要
Abstract
This paper uses a non-negative least-squares method based on sparse matrix, to solve the dwell time in computer controlled optical surfacing(CCOS) of optical elements with large diameter and microstructure, and the regularization of the meth-od is researched. The simulation results reveal that the large-scale non-negative least-squares method based on sparse matrix has higher accuracy and efficiency, in contrast with the traditional non-negative least-squares method. The RMS of surface residual er-ror converges to 0. 067 wavelength, when the method is used to simulate the manufacturing of an optical workpiece with large di-ameter, microstructures and average surface amplitude of 1. 177 6 wavelength.关键词
