Paper Abstract

Photopolymerizable systems were developed in Mulhouse as holographic recording materials. The direct generation of images with no post-treatment nor repositioning is their most attractive feature. Such media are ideally suited for real time interferometry. Compromises for definition of the exposure parameters were established, taking into account the desired diffraction efficiency and the exposure time that could not be lower than a few tenths of a second. On the other hand, the self-processing system was optimized for the recording of off-axis holographic lenses. With such a n end in view, the aim was not to attain the shortest and easiest handling time but the highest diffraction efficiency and the lowest optical noise. The diffracted beams were sharply focused and diffraction efficiencies higher than 80 percent were obtained at 514 nm. Since the chemical composition and the method of conditioning are very flexible, they can be adapted to meet the requirements for various applications.
