Paper Abstract

In this paper, based on the photosensitive characteristics of a photopolymer recording material — Photoetching Cellulose Film (PCF), some effective post-processing techniques such as delay-development, ultraviolet (UV) uniform post-exposure, and chemical etching development, are investigated to increase the diffraction efficiency and relief depth of PCF micro-optical and holographic elements. The delay development technique can obtain an enhancement factor of more than 50%, while both the UV post-exposure and chemical development techniques can achieve up to 100% enhancement factor.
