Laser-Based Optical Associative Memories

摘要: A new approach to architecture based on the use of a laser as nonlinear discriminator for all-optical, auto- and hetero-associative memories is presented. The operates in regime spatial multistability, i.e., coexistence different stable stationary states. Numerical calculations simplest situations indicate that able decide which its states most similar field pattern injected into itself. combined with linear system composed lenses, holograms, pinhole mask. memory constituted certain number images are stored one holograms one-to-one correspondence laser. task part (a) convert an arbitrary image offered appropriate pattern, laser; (b) beam, emerges from laser, corresponding memory.
