Advancing Curvature Adaptive Optics

Abstract

We have taken important steps in attacking two key issues in curvature adaptive optics as applied to the SSA problem: 1. We have set up a high speed wave front characterization camera capable of measuring Shack-Hartmann data over the DM pupil at speeds in excess of 10,000 frames per second. 2. We have purchased and are integrating into our system an EMCCD to replace an inefficient combination of a fiber coupled lenslet array and avalanche photo-diodes.
