Abstract

Dichromated gelatin (DCG) is nov well established as the preferred material for quality holographic optical elements in avionic applications. DCC is an extremely flexible holographic material and a wide range of properties can be achieved, however, associated with this flexibility is a considerable degree of process sensitivity. In this paper we discuss some of the process control and monitoring techniques used to help establish a production viable process and achieve the high performance and tolerance requirements of avionic holographic optical elements. The range of holographic optical element properties that can now be achieved in production volumes across a film range from 4 microns to several hundred microns is reviewed.
