Abstract
In this paper a high-efficiency diffraction hologram fabricated using digital image processing technology in dichromated gelatin (DCG) is described. A charge coupled device (CCD) camera and frame capture card were used to obtain the holographic grating processing parameters using hologram manufacturing process procedures. With this image system the transmittance of the DCG solution can be measured, the uniformity and thickness of the emulsion on the glass plate can be controlled, the hardness of the prepared gelatin layer analysed and the variations in the hologram diffraction efficiency monitored. The experimental results verified that this image system provides an economical and effective method for producing a DCG hologram.
