SYSTEM AND METHOD FOR MANUFACTURE OF MULTIPLE HOLOGRAPHIC ELEMENT

摘要

PURPOSE: To manufacture a highly accurate and efficient multiple holography element. CONSTITUTION: This system is provided with a process for forming a master multiple holography element 28 having an absorbing grating pattern for generating a prescribed refractive index pattern over the element 28 and a process for orientating a recording beam to a photopolymer layer through the element 28. The absorbing grating pattern of the element 28 adjusts the recording beam and the adjusted recording beam generates a monomer in the photopolymer to form a monomer pattern for generating a prescribed refractive index pattern over the photopolymer layer. The system is also provided with a process for fixing the monomer of the photopolymer layer on the monomer pattern to form a copy of the element 28 on the monomer pattern and a process for removing the photopolymer layer from the element 28.
