Abstract

The performance of computer-generated binary holograms recorded on a 128x128 pixel supports was studied experimentally, with the objective of recording holograms on spatial light modulators such as the Semetex SIGHT-MOD for rotation-invariant pattern recognition. Since the performance was unsatisfactory, a new method of diagonal coding was introduced. This method yields much better results, as it allows a more accurate phase quantization. Experimental results of computer simulations show that high-speed rotation-invariant recognition of simple shapes is possible with such holograms.
