Reconstruction methods for the phase-shifted Zernike wavefront sensor
Vincent Chambouleyron, Mahawa Cissé, Maïssa Salama +8
The Zernike wavefront sensor (ZWFS) stands out as one of the most sensitive optical systems for measuring the phase of an incoming wavefront, reaching photon efficiencies close to…
