Wavefront Curvature Sensing From Image Projections - Buffington, Jonathan C

. .

Résumé :

This research outlines the development and simulation of a signal processing approach to real time wavefront curvature sensing in adaptive optics. The signal processing approach combines vectorized Charge Coupled Device (CCD) read out with a wavefront modal estimation technique. The wavefront sensing algorithm analyzes vector projections of image intensity data to provide an estimate of the wavefront phaseas a combination of several low order Zernike polynomial modes.
