Abstract

UN DISPOSITIVO DE M X N ESPEJOS ACCIONADOS POR MEMBRANAS FINAS PARA UTILIZAR EN UN SISTEMA DE PROYECCION OPTICA COMPRENDE UNA MATRIZ ACTIVA; UN DISPOSITIVO DE M X N ESTRUCTURAS DE ACCIONAMIENTO POR MEMBRANAS FINAS, CADA UNA DE LAS CUALES INCLUYE AL MENOS UNA CAPA DE MEMBRANA FINA DE UN MATERIAL INDUCTOR DE MOVIMIENTO; UN PAR DE ELECTRODOS CADA UNO DE LOS CUALES ESTA PROVISTO SOBRE LA PARTE SUPERIOR E INFERIOR DE LA CAPA INDUCTORA DE MOVIMIENTO DE MEMBRANA FINA; UN DISPOSITIVO DE M X N MIEMBROS DE SOPORTE CADA UNO DE LOS CUALES SE UTILIZA PARA SUJETAR LAS ESTRUCTURAS DE ACCIONAMIENTO EN SU LUGAR POR MEDIO DE RESORTES CANTILEVER, Y TAMBIEN PARA CONECTAR ELECTRICAMENTE DICHAS ESTRUCTURAS Y LA MATRIZ ACTIVA; UN DISPOSITIVO DE M X N MIEMBROS SEPARADORES CADA UNO DE LOS CUALES SE MONTA SOBRE LA SUPERFICIE SUPERIOR DE CADA UNA DE LAS ESTRUCTURAS DE ACCIONAMIENTO EN SU EXTREMO DISTAL; Y UN DISPOSITIVO DE M X N CAPAS DE ESPEJO PARA REFLEJAR LOS RAYOS DE LUZ ESTANDO CADA UNA DE ELLAS ASEGURADA SOBRECADA MIEMBRO SEPARADOR DE LAS ESTRUCTURAS DE ACCIONAMIENTO. SE APLICA UNA SEÑAL ELECTRICA A TRAVES DE LA CAPA DE MEMBRANA FINA DEL MATERIAL INDUCTOR DE MOVIMIENTO LOCALIZADA ENTRE EL PAR DE ELECTRODOS DE CADA UNA DE LAS ESTRUCTURAS DE ACCIONAMIENTO, PROVOCANDO SU DEFORMACION, LA CUAL INCLINARA EN CAMBIO LA CAPA DE ESPEJO ASEGURADA A SU MIEMBRO SEPARADOR.
