A New Algorithm of Combining for Spatial Coherent Beams

摘要

Abstract: A Peak-Rate (PR) algorithm of combining for spatial coherent beams is presented whichis based on the abstraction of image's character captured by CCD. The algorithm is simulated andapplied in experiment and two collimated beams with piston aberration are coherently combined.Piston aberration is introduced into two coherent beams and Active Segmented Mirrors (ASMs) areused to correct it by PR algorithm. The experiment results indicate that far-field interferometricpattern is stable and beams are coherently combined accurately.
