Abstract

UN TRANSMISOR DE POSICION OPTICA CONTIENE UN CODIFICADOR (36). EN EL CODIFICADOR SE CONDUCE UN HAZ (44) DE LUZ. LA CODIFICACION DE LA PARTE CODIFICADORA (36) ORIGINA EN LOS HACES DE LUZ (44) REFLEJADOS CON DIFERENCIA DE TIEMPO DE MARCHA HACES DE LUZ INFERIORES PUEDEN PASAR SOBRE LA SUPERFICIE DE LAS PIEZAS (36) CODIFICADORAS A TRAVES DE LAS PIEZAS SUPERFICIALES GRADUADAS. LA DIFERENCIA DE TIEMPO DE MARCHA ES MAYOR QUE LA LONGITUD DE COHERENCIA DE LA LUZ DE MANANTIAL (62). EL HAZ DE LUZ REFLEJADO SE CONDUCE POR UNA DISTRIBUCION (42) DE RADIACION SOBRE UN INTERFEROMETRO PARA LA DETECCION DE LA DIFERENCIA DE TIEMPO DE MARCHA. A TRAVES DE LA MODIFICACION RAPIDA DEFINIDA EN EL INTERFEROMETRO SE POSIBILITAN EN RECORRIDOS DIFERENCIADOS DETERMINANDO INTERFERENCIAS ENTRE HACES DE LUZ INFERIOR PUEDEN OBTENERSE SEÑALES DE POSICION DE LAS INTERFERENCIAS PRODUCIDAS.
