17 September 2002Dynamic hologram recording characteristics in photopolymer films
In this report, recent experimental results on photopolymer, holographic recording material provided by Technical Institute of Physics and Chemistry Chinese Academy of Sciences, were presented. High-diffraction-efficiency unslanted gratings were made. The recording characteristics of the material are discussed in detail in terms of sensitivity, diffraction efficiency, Bragg angle, dynamical range (Δ n). Variation of diffraction efficiency with different incident intensity are discussed. Finally, one data page in the form of 256*256 pixel array has been stored and retrieved with low bit-error rate in this photopolymer media.
