Abstract

COMPRENDE UNA SUPERFICIE S QUE FORMA PARTE DEL CUERPO (2) Y UN SOPORTE (1) QUE FORMA PARTE DE LA ESTRUCTURA (3), DENTRO DEL CUAL SE HALLAN ALOJADOS MEDIOS PARA ILUMINAR LA SUPERFICIE S Y RECIBIR LOS HACES DE LUZ REFLEJADOS POR DOS PORCIONES DE ESTA SUPERFICIE. ESTOS MEDIOS COMPRENDEN DOS LENTES (4, 5) Y DOS FIBRAS OPTICAS (6, 7) ACOPLADAS A LAS LENTES POR UN EXTREMO Y POR EL OTRO A UNA FUENTE DE LUZ G MEDIANTE UN ACOPLADOR (29). LOS HACES DE LUZ EMITIDOS POR LAS LENTES (4, 5) SON REFLEJADOS POR LA SUPERFICIE S EN FUNCION DE LA POSICION DEL CUERPO (2), RECIBIDOS POR LAS PROPIAS LENTES Y RETRANSMITIDOS POR LAS FIBRAS OPTICAS (6, 7) PARA SU ELABORACION ULTERIOR. ES DE CONSTRUCCION SENCILLA Y POCO SENSIBLE A LAS INTERFERENCIAS. SE APLICA PARA DETECTAR LA POSICION RELATIVA DE DOS ELEMENTOS MECANICOS.
