Abstract

SE DESCRIBEN UN METODO Y UN APARATO PARA DESVIAR LUZ, QUE PROPORCIONAN UNA REPRESENTACION GRAFICA DE INTENSIDAD OPTICA-POSICION, ASI COMO POSIBILIDADES DE CONMUTACION OPTICA. SE PROPORCIONA UNA AGRUPACION DE MODULOS DE GRADIENTE DE TENSION (24, 26, 28) EN UNA CAPA DE MATERIAL ELECTRO-OPTICO (52), TAL COMO DE CRISTALES LIQUIDOS, ESTABLECIENDO GRADIENTES VARIABLES DE TENSION ESPECIALES Y CAMPOS ELECTRICOS ASOCIADOS EN UNA DIRECCION TRANSVERSAL A LA LUZ QUE ENTRA (58). LOS GRADIENTES DE TENSION SON HECHOS VARIAS DE ACUERDO CON LAS INTENSIDADES OPTICAS EN LUGARES CORRESPONDIENTES DE LA LUZ RECIBIDA (58), DANDO COMO RESULTADO SALIDAS OPTICAS QUE VARIAN DE DIRECCION DE ACUERDO CON LOS CAMBIOS DE GRADIENTE DE TENSION. LAS SALIDAS DIRECCIONALES SON ENFOCADAS ENTONCES PARA PRODUCIR UNA REPRESENTACION POSICIONAL (64, 66, 68) DE LAS INTENSIDADES DE LA LUZ QUE ENTRA. LOS GRADIENTES DE TENSION SON ESTABLECIDOS, PREFERIBLEMENTE, POR UNA AGRUPACION (50) DE ELCTRODOS INTERCALADOS Y UN CONTRA-ELECTRODO (54)EN LADOS OPUESTOS DEL CRISTAL LIQUIDO (52). SE DESCRIBEN REALIZACIONES DE VALVULAS REFLECTORAS Y TRANSMISORAS DE LUZ, EN LAS QUE LOS MODULOS DE GRADIENTE DE TENSION FORMAN DIVISORES DE TENSION CON UNA CAPA FOTOCONDUCTORA SUBYACENTE (56). SE DESCRIBE, ASIMISMO, UN CONMUTADOR OPTICO DE FIBRAS.
