A general design rule of implementing the logic gates is obtained from the dimensionless intensity distribution of interference fringes formed by multiple equally spaced slits. Various designs of logic gates such as NAND, XOR, and so on are presented. The feasibility of implementing the logic gates and their exemplary applications to edge detection are demonstrated in several proof-of-principle experiments. System issues are discussed. © 1998 Society of Photo-Optical Instrumentation Engineers.application/pdf964997 bytesapplication/pdfen-USOptical computing; Optical interference; Optical logic gatesjournal article10.1117/1.6019352-s2.0-0010967438WOS:000072530200037http://ntur.lib.ntu.edu.tw/bitstream/246246/85667/1/16.pdf
