Computer Generated Holograms

Computer-generated holography (CGH) is the method of digitally generating holographic interference patterns. A holographic image can be generated e.g. by digitally computing a holographic interference pattern and printing it onto a mask or film for subsequent illumination by suitable coherent light source.

We have studied the problem of the encoding of CGH in substrates with limited modulation capability, like laser printers, or Liquid Crystal Spatial Light Modulators (LCSLM). We have developed a method to obtain the diffraction efficiency in the presence of amplitude and phase mismatching, that it is especially important in LCSLM. We have used these CGH mainly for pattern recognition. We have also studied a labeling technique with increased depth of focus for non-planar surfaces.
