Abstract

We studied 100 ${\mu}{\textrm}{m}$ DuPont photopolymers (HRF-150-100) for characteristics of hologram formation and shrinkage at 514 nm with various grating spacings and light intensities. For combinations of rotational and angular multiplexings, we employed two different techniques by rotating the photopolymer and the reference beam. We also performed shift-rotational multilpexing with the rotating reference beam.

본 연구에서는 514 nm 레이저를 이용하여 DuPont HRF-150-100 포토폴리머의 홀로그램 형성에 대한 격자간격과 빛의 강도에 따른 특성과 입사각에 따른 수축을 둥을 측정 분석하였다. 또한 폴리머를 직접 회전시키는 시스템 뿐 아니라 기준 빔을 직접 회전시키는 시스템으로 각-회전 다중화 홀로그램 저장을 수행하였으며 이동최전 다중화와의 결합에 C19의한 저장도 수행하였다.
