Experimental validation of optimization concepts for focal-plane image processing with adaptive optics

Korkiakoski, Visa; Keller, Christoph U; Doelman, Niek; Fraanje, Rufus; Andrei, Raluca M; Verhaegen, Michel


We show experimental results demonstrating the feasibility of an extremely fast sequential phase-diversity (SPD) algorithm for point sources. The algorithm can be implemented on a typical adaptive optics (AO) system to improve the wavefront reconstruction beyond the capabilities of a wavefront sensor by using the information from the imaging camera. The algorithm is based on a small-phase approximation enabling fast numerical implementation, and it finds the optimal wavefront correction by...[Show more]
