Nonlinear wavefront reconstruction from a pyramid sensor using neural networks
Alison P. Wong, Barnaby R. M. Norris, Vincent Deo +7
The pyramid wavefront sensor (PyWFS) has become increasingly popular to use in adaptive optics (AO) systems due to its high sensitivity. The main drawback of the PyWFS is that it i…
