HOLOGRAPHIC RECORDING CHARACTERISTICS OF AN ACRYLAMIDE-BASED PHOTOPOLYMER

Recent research on an acrylamide-based photopolymerizable holographic recording material is presented. The recording characteristics of the material are discussed in detail in terms of sensitivity, diffraction effciency, recording linearity, resolution limit, and sources of noise . Although the resolution is not sufficient for reflection holography, the recording characteristics are excellent far transmission gratings . The material was found to suffer no shrinkage during recording, and high-diffraction-efficiency slanted gratings were made. Finally, the s uitability of this self-developing material to both double-exposure an d real-time holographic interferometry is demonstrated. (C) 1997 Optic al Society of America.
