Abstract

The optical performance of a holographic projection system is analyzed by a physical optics simulation code. This holographic projector is used to produce micro-optical devices which are generated by a photolytic process involving exposure and development. These devices can be used as a new generation of directional light filters and monolithic micro-channel optical arrays. This projection system consists of a laser, a beam expander, a beam reshaping system which reshapes the Gaussian beam profile of the laser into a uniform beam profile, a holographic diffraction grating which is used to produce multiple beams, and an interferometric optical system behind the grating. This interferometric optical system creates broadly diverging cones of light which mutually overlap creating a three-dimensional standing wave interference pattern. A diazo-acid-coupler coated substrate can be placed within the overlapping cones of light so that an interference pattern may be recorded within the substrate coating to produce micro-optical devices or directional light filters.
