Breaking of Wavelength-Dependence in Holographic Wavefront Sensors Using Spatial-Spectral Filtering
Sensors, 2023 Nowadays, wavefront sensors are widely used to control the shape of the wavefront and detect aberrations of the complex field amplitude in various fields of physics. However, almost all of the existing wavefront sensors work only with quasi-monochromatic

Compensation of Non Common Path Aberrations on a pyramid wavefront sensor with an Adaptive Lens. [PDF]
, 2022 Closed loop systems based on the Pyramid wavefront sensor (P-WFS) can reach very high sensitivity respect to other wavefront sensors. The sensitivity increases as the Point Spread Function (PSF) on the tip of the pyramid gets smaller. Therefore, it is

Estimation and correction of wavefront aberrations using the self-coherent camera: laboratory results [PDF]
, 2013 Context. Direct imaging of exoplanets requires very high contrast levels, which are obtained using coronagraphs. But residual quasi-static aberrations create speckles in the focal plane downstream of the coronagraph which mask the planet.

Ocular higher-order aberrations and visual performance [PDF]
, 2011 Since adaptive optics was first used to correct the monochromatic aberrations of the eye over a decade ago there has been considerable interest in correcting the ocular aberrations beyond defocus and astigmatism.

Describing ocular aberrations with wavefront vergence maps\ud
, 2009 A common optometric problem is to specify the eye’s ocular aberrations in terms of Zernike coefficients and to reduce that specification to a prescription for the optimum\ud sphero-cylindrical correcting lens. The typical approach is first to reconstruct
