“…It is known that DCG is more sensitive to long-UV light than to visible light [ 2 , 3 ] therefore, a UV mercury metal-halide pressure lamp was used in the recording. In the following set of experiments, the light source was an extended one, as shown in Figure 2 b.…”

“…In 1968, Shankoff [ 2 , 3 ] proposed the use of dichromated gelatin plates (DCG plates) as the material to record holograms. He found diffraction efficiencies of 33% for thin phase gratings and 95% for thick holograms.…”

“…Gravity settling method was adopted for casting the films [4]. The films were casted on dirt-free and perfectly clean microscopic glass slides of dimension 75mm X 25mm X 1.35mm.…”

“…Dichromated gelatin forms thick-phase holograms which transmit effectively all the incident light but whose fringes spatially vary the phase of the transmitted wavefront. Brandes et al (1969) have described the formation and development of dichromated gelatin films and they suggest that the combination of water and isopropanol used on gelatin hardened with ammonium dichromate results in the best photographic speeds with the highest signal to noise ratios, which may, in fact, be up to five times greater than 649F emulsion.…”
