Focal-plane wavefront sensing with high-order adaptive optics systems

Korkiakoski, Visa; Keller, Christoph U.; Doelman, Neik; Kenworthy, M A; Otten, Gilles; Verhaegen, Michel

Description

We investigate methods to calibrate the non-common path aberrations at an adaptive optics system having a wavefront-correcting device working with an extremely high resolution (larger than 150x150 correcting elements). We use focal-plane images collected successively, the corresponding phase-diversity information and numerically efficient algorithms to calculate the required wavefront updates. Different approaches are considered in numerical simulations, and laboratory experiments are shown to...[Show more]
