Abstract

TRANSDUCTORES DE DESPLAZAMIENTO CODIFICADOS OPTICAMENTE. COMPRENDEN UNA ESCALA CON REGIONES DE CARACTERISTICAS OPTICAS DIFERENTES: UNA FUENTE DE HAZ DE RADIACION DIRIGIDA HACIA LA ESCALA Y UNA PLURALIDAD DE ELEMENTOS DETECTORES DISPUESTOS PARA RECIBIR RADIACION DE LA ESCALA. LOS ELEMENTOS DETECTORES Y LA FUENTE DEL HAZ DE RADIACION SE SITUAN EN EL MISMO LADO DE LA ESCALA, DE MODO QUE LA RADIACION SE REFLEJA EN LA ESCALA Y PASA AL INTERIOR DE LOS DETECTORES. UN GRUPO DE REGIONES DE UNA DETERMINADA CARACTERISTICA OPTICA COMPRENDEN ELEMENTOS DE PARES DE LINEAS CON UNA ANCHURA ESPECIFICA, ASI COMO MEDIOS QUE ESTAN FUNCIONALMENTE ASOCIADOS CON EL DETECTOR PARA HACER OPTIMA LA CORRESPONDENCIA ENTRE EL NUMERO DE ELEMENTOS DE DETECCION EN LOS DETECTORES Y LA ANCHURA DE UN ELEMENTO DE PARES DE LINEAS PERTENECIENTE A LA ESCALA.
