Parameters of the fine-structure error of large disk-shaped active elements when they are shaped with a compact tool

摘要

This paper discusses the features of using a small tool to shape the working surfaces of compact disk-shaped active elements. The results of measuring the fine-structure error are presented. An algorithm is presented for numerically modelling the wave-front distortions of a beam transmitted through an arbitrary number of elements that contain fine-structure error, along with the results of the modelling.
