Paper Abstract

Dispersed fringe sensor (DFS) using broadband point source can unambiguously estimate piston to several hundred microns. We demonstrate a rapid technique to analyze the data from a DFS. The technique is less susceptible to higher order aberrations and returns the average phase difference between two aperture elements.
