Dichromated gelatin has been shown to be a useful photosensitive holographic recording material (1,2,3). We are investigating some characteristics of dichromated gelatin, with particular attention to the diffraction efficiency (typically 95 - 98%), reflection bandwidth and incident angle sensitivity. The dichromated gelatin preparation and processing techniques that affect these parameters will be included. Applications for these holographically produced reflection filters include head-up displays, laser protection eyewear and holographic laser beam combiners.
