Abstract
EN UN METODO PARA RECONOCER UNA PALABRA BINARIA CODIFICADA OPTICAMENTE, LA PALABRA ES ELEGIDA DE UN SUBGRUPO DE PALABRAS BINARIAS PARA LAS CUALES W{ZT}T=0 SI W=T, W{ZT}T=1 SI W ES DISTINTO DE T, SIENDO VERDADERO, DONDE T ES LA PALABRA OBJETIVO, W ES LA PALABRA A COMPARAR Y {ZT} ES LA FORMULA OPERATIVA (I). LA PALABRA SE RECONOCE LLEVANDO A CABO EN EL AMBITO OPTICO UNA OPERACION BOOLEANA AND SOBRE LOS BITS. LA OPERACION SE LLEVA A CABO SOBRE LA PALABRA A RECONOCER Y EL COMPLEMENTO DE LA PALABRA OBJETIVO. LA OPERACION AND PUEDE SER LLEVADA A CABO INTRODUCIENDO LA PALABRA A RECONOCER Y LA PALABRA OBJETIVO EN UN CRISTAL NO LINEAL Y DETECTANDO LA SEGUNDA SALIDA ARMONICA DESDE EL CRISTAL. EL COMPLEMENTO DE LA PALABRA OBJETIVO PUEDE SER GENERADO MEDIANTE UNA RED DE FORMACION DE PALABRAS FIJA. EL METODO PUEDE APLICARSE PARA RECONOCER LA DIRECCION DE UN PAQUETE EN UNA RED OPTICA.
