Programmable OASLM as a Novel Sensing Cellular Computer

We have developed a novel type of correlators named searching correlator (SC) (Tokes et al., 2003) using bacteriorhodopsin (BR) as a dynamic rewritable and multiply readable holographic material. Our POAC (programmable optical array computer) model can perform highly parallel optical correlations and feedforward CNN operations. However, to keep pace with digital technologies (Moore´s law); newer, more effective materials are needed. The sensitivity, diffraction efficiency and cycle time are the most critical parameters of the dynamic holographic materials to be used in 2D optical processors. Only highly engineered, composite media, such as multiple quantum well optically addressable spatial light modulator (MQW-OASLM), liquid crystal embedded polymers or photonic crystal devices will be able to satisfy all of the requirements. However, these devices could not reach yet the stage of a commercial product. That is why we are working on a new approach for realizing competitive optical CNN processor architectures by integrating a high-end CMOS camera and an LCD micro-display with an embedded FPGA processor. Embedding this PRC-OASLM, our present feed-forward-only optical CNN processor architecture can be developed to a nonlinear feedback architecture
