Paper Abstract

A small low speed wavefront sensor has been built for Harvard Smithsonian Observatory for astronomical observing. The sensor measures wavefronts using a small lenslet array to focus light as spots on a detector array. The position of these spots are used to measure the wavefront distortion. The detector array output is digitized and processed by a high speed image processor. The processor outputs the directional derivatives of the wavefront in the X and Y directions.
