System and method for holographic wave-front printing

Abstract

A holographic recording system includes a linear translation stage configured to position a holographic material layer, a light source configured to emit a laser beam, a beam splitting subsystem configured to split the laser beam into a first light beam and a second light beam and direct the second light beam towards the holographic material layer, a spatial-light modulator configured to implement a fringe pattern that modulates the first light beam to generate an object beam, a filter configured to filter the object beam, a demagnification optical subsystem configured to demagnify the object beam, and a switchable grating stack configurable to direct the object beam to a set of directions towards the holographic material layer to interfere with the second light beam. In some embodiments, the switchable grating stack includes a plurality of polarization gratings and/or a plurality of switchable waveplates arranged in a stack.
