Holographic wavefront sensors

Quantum Electronics, 2020
Abstract A brief historical review of the first designs of holographic wavefront sensors (WFS’s) and the concepts lying in their basis is presented. The main directions in the development of these sensors are highlighted and considered.

Fourier wavefront reconstruction with a pyramid wavefront sensor

Adaptive Optics Systems VI, 2018
Using Fourier methods to reconstruct the phase measured by a wavefront sensor (WFS) can significantly re- duce the number of computations required, as well as easily enable predictive reconstruction methods based on knowledge of the adaptive optics system, atmospheric turbulence and wind profile. Previous work on Fourier re- construction has focused on

Holographic wavefront sensor

SPIE Proceedings, 2005
In this talk we will present a new zonal wavefront sensor. The device consists of a multiplexed hologram which can reconstruct multiple diffracted beams to an image plane with the input of a single object beam. In operation, a wavefront incident on the hologram is divided up into various output beams according to the presence and strength of particular
