Paper Abstract

Rotation invariant pattern recognition based on the holographic associative memory (HAM) is presented. Patterns are stored in HAM by using the scattered light holography in which a mother pattern is associated holographically with its several(nine in this paper) mtated patterns. In the experiment the rotated pattern is stored in different part of recording medium. For the input pattern rotated by any angle the associated mother pattern is reconstructed. Two mother patterns are stored in this manner.
