Abstract

See full text

Provided are methods for replication (copying) of volume Holographic Optical Elements (HOE) using a master hologram in optical contact with a prism, wherein the master hologram comprises distinct object and reference beam coupling elements, and wherein in the replication process light is coupled from one face of the prism and transmitted through another face of the prism using the distinct object and reference beam coupling elements. Methods for making the master hologram by sequentially forming the distinct object and reference beam coupling elements therein are provided. Further methods for encoding aperture functions directly to the master hologram are provided. Yet further methods provide for forming a copy HOE in an array configuration using a step-and-repeat method wherein the copy HOE is translated laterally by a specified distance before the next exposure is made.
