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
