Dynamic tool influence function on SiC mirror surfaces for space optical telescopes using orthogonal velocity tool

Abstract

The quality of mirror surface is a crucial factor in enhancing the optical performance of space telescopes, and the Tool Influence Function (TIF) is an important parameter that determines the surface quality by measuring the unit removal volume. Although TIF studies have traditionally been performed under static conditions, there is a growing interest in studying dynamic TIF using a moving polishing head. In this presentation, we report on initial dynamic TIF patterns on SiC mirror surfaces for Space Optical Telescopes using the Orthogonal Velocity Tool (OVT) at KASI.
