title: Optical cellular processor architecture. 2: Illustration and system considerations.
abstract: In the first paper of this series, we proposed a definition for the concept of 2-D optical cellular processors. In this second part we present an optical experimental setup capable of implementing a binary pattern recognizer. A 2-D hologram array is used in conjunction with a multiplexed holographic illumination for the interconnection and makes the system easily programmable. Thick phase holograms on dichromated gelatin cause distortion and their field of view is constrained by the Bragg effect. These problems are investigated in relation to all the system aberrations and a set of optimal parameters for one distortion-free configuration is given. Experimental results are shown.
