HIGHLY SENSITIVE PHOTOPOLYMERIZABLE DRY FILM FOR USE IN REAL-TIME HOLOGRAPHY

A photopolymerizable holographic material has been obtained and charac terized using agent N,N'-dihydroxiethylenbisacrylamide as crosslinking . A sensitivity of 5 mJ/cm(2) and a diffraction efficiency around of 7 0% have been reached for holograms recorded at 633 nm with a spatial f requency of 1000 lines/mm. High sensitivities can be obtained with low intensities, and this is important in applications such as holographi c interferometry and the fabrication of holographic optical elements.
