Abstract
UN DISPOSITIVO DE CRISTAL LIQUIDO ESTA FORMADO POR LA APLICACION DE UNA PELICULA DE ALINEAMIENTO QUE COMPRENDE UNA POLIAMIDA CONTENIENDO FLUOR, QUE TIENE UN SUSTITUTIVO QUE CONTIENE FLUOR EN SU MITAD ORIGINADO DE UNA DIAMINA SOBRE AL MENOS UNO DE UN PAR DE SUBSTRATOS QUE INTERCALAN UN CRISTAL LIQUIDO ESMECTICO CHIRAL. PREFERIBLEMENTE, SE PROPORCIONAN LOS SUBSTRATOS RESPECTIVOS CON DICHAS PELICULAS DE ALINEAMIENTO DE POLIAMIDA CONTENIENDO FLUOR QUE HAN SIDO FROTADOS EN DIRECCIONES QUE ESTAN SUSTANCIALMENTE PARALELAS UNA CON LA OTRA E IDENTICAS UNA CON LA OTRA, O QUE FORMAN INTERSECCION UNA CON LA OTRA EN UN PEQUEÑO ANGULO DE INTERSECCION EN DIRECCION CONTRARIA A LAS AGUJAS DEL RELOJ. EL DISPOSITIVO DE CRISTAL LIQUIDO ASI FORMADO MUESTRA UNA REPRESENTACION DE ALTO CONTRASTE, ESPECIALMENTE MEDIANTE ARRASTRE DE MULTIPLEXADO, LIBRE DE IMAGENES A POSTERIORI DEBIDO A SU RAPIDA RESPUESTA.
