Optimal Shack-Hartmann Wavefront Sensing For Low-Light-Levels

Abstract

This report results from a contract tasking Physics Laboratory, University of Kent at Canterbury as follows: The contractor will investigate optimal estimation techniques for low light level wavefront sensing. He will analyze the sensitivity gains achievable in shack-hartmann wavefront sensors using bayesian estimators and compare the results with those achieved using a standard least squares approach. Investigate optimal wavefront sensor sub-aperture geometries.
