Abstract

DISPOSITIVO PARA MEDIR UNA MAGNITUD FISICA Y PROPORCIONAR LA TRANSMISION A DISTANCIA DEL VALOR DE LA MAGNITUD FISICA DETECTADA. EL VALOR DE UN MAGNITUD FISICA SE MANIFIESTA A DISTANCIA DE LA ZONA DONDE ES DETECTADA POR MEDIO DE UN SENSOR OPTICO POLARIMETRICO (10) Y PARA ESTE FIN, EL DISPOSITIVO SEGUN LA INVENCION PREVEE COMO ELEMENTO TRANSMISOR UNA UNICA FIBRA OPTICA (2) POR LA CUAL SE TRANSMITEN TANTO LA SEÑAL OPTICA DE MEDIDA (5) COMO LA SEÑAL OPTICA DE REFERENCIA (4). DE ESTA MANERA, EL ELEMENTO DEL DISPOSITIVO INMERSO EN EL CAMPO DE LA MAGNITUD FISICA A MEDIR NO REQUIERE LA PRESENCIA DE NINGUN CONECTOR OPTICO, CONSIGUIENDOSE UNA DISMINUCION EN SU TAMAÑO PARA REDUCIR EN CONSECUENCIA AL MINIMO LA ALTERACION CAUSADA EN EL CAMPO DE LA MAGNITUD FISICA A MEDIR Y POR LO TANTO INCREMENTAR LA EXACTITUD DE LA MEDIDA EN EL DISPOSITIVO.
