Creation of raster relief structures on silver-halide photographic emulsions with the help of two-dimensional holographic gratings

摘要

A method for fabrication of a microlens raster with full filling on photographic plates PFG-01 is proposed. A twodimensional holographic crossed grating (TDHG) with improved imaging properties is used as an image multiplying optical element. In order to create the improved TDHG, we have proposed a special technique for photographic emulsion layer treatment. The light intensity distribution from the display image was projected onto a light-sensitive material using the TDHG. After the development of the photographic plates, either hardening bleaching or short-wave ultra-violet illumination is used for relief creation.
