Focal-plane wavefront sensing with high-order adaptive optics systems
Visa Korkiakoski, Christoph U. Keller, Niek Doelman +3
We investigate methods to calibrate the non-common path aberrations at an adaptive optics system having a wavefront-correcting device working at an extremely high resolution (large…

Fast & Furious focal-plane wavefront sensing
Visa Korkiakoski, Christoph U. Keller, Niek Doelman +3
We present two complementary algorithms suitable for using focal-plane measurements to control a wavefront corrector with an extremely high spatial resolution. The algorithms use l…
