Abstract

A method includes providing light from a light source and separating the light into a first portion of the light and a second portion of the light that is spatially separated from the first portion of the light. The method also includes transmitting the first portion of the light through a first set of optical elements to provide a first wide-field beam, transmitting the second portion of the light through a second set of optical elements to provide a second wide-field beam that is spatially separated from the first wide-field beam, and transmitting the second wide-field beam through a third set of optical elements to provide a plurality of separate light patterns. The method further includes concurrently projecting the first wide-field beam and the plurality of separate light patterns onto an optically recordable medium to form a holographic medium.
