摘要：
In this paper, A full-color Denisyuk-type hologram using photopolymer has been recorded by the sequential exposure method. The photopolymer's optical characteristics show that inhibition periods of the photopolymer at three lasers are different in the same beam intensity. To increase the average diffraction efficiency of a full-color holographic optical element ( HOE), the three lasers should be sequentially exposed to the photopolymer. The experimental results show that the average efficiency of a full-color reflection HOE is 59.6% and the standard deviation is 2.1. Also, the full-color hologram recorded in a one-layer photopolymer can reconstruct a high-quality image.
