COMPUTER-ORIGINATED POLARIZING HOLOGRAPHIC OPTICAL-ELEMENT RECORDED IN PHOTOPOLYMERIZABLE LAYERS

The photosensitive system that is used in most cases to produce hologr aphic optical holograms is dichromated gelatin. Other materials may be used, in particular, photopolymerizable layers. In the present invest igation, we set out to use the polymer developed in the Laboratoire de Photochimie Generale in Mulhouse in order to duplicate a computer-gen erated hologram. Our technique is intended to generate polarizing prop erties. We took into account the fact that no wet chemistry processing is required; grating fringe spacings are not distorted through chemic al development.
