Abstract

An optical computing method for string data matching applicable to genome information processing is presented. With encoding 1D data into spatial code patterns, moire fringes between two different coded patterns provide information on the correspondence of the original data, which is useful for string alignment in genome analysis. A new code set for the spatial coding is capable of processing complementary base-pairing DNA sequences. Results of the preliminary experiments are shown to verify effectiveness of the method. Processing performance is evaluated with a simplified model. Finally, two optoelectronic implementations are presented for future directions.
