Neural NOPE: a physics-informed neural network approach to mitigate nonlinearity in pyramid wavefront sensing for adaptive optics
Pyramid wavefront sensors (PWFSs) are key components of adaptive optics (AO) systems for next-generation extremely large telescopes (ELTs). However, their nonlinear behavior can degrade image quality under strong atmospheric turbulence, especially when conventional matrix vector multiplication (MVM) methods are used. T...
