Design of a White Light Radial Shear Interferometer for Segmented Mirror Control

摘要

This paper presents the optical description of a white light radial shear interferometer for use in the control of segmented mirror systems. White light from a segment of the mirror under control is caused to interfere with light from other segments. The resulting white light fringe position is modulated so that an error signal corresponding to wavefront offset may be generated.
