Figure control for a fully segmented telescope mirror

Not Accessible

Your library or personal account may give you access

Abstract

A system is described to control the figure of a large telescope primary mirror that is composed of many individual segments. The geometry considered, employing hexagonal mirrors, allows a simple and economical control system. The system is shown to be reliable and effective in continuously maintaining the figure to the precision required for optical astronomy.
