Abstract

ESTA INVENCION TRATA DE UN DISPOSITIVO PARA MEDIR LA POSICION Y EL DIAMETRO DEL FILAMENTO EN UN OVILLO DEL FILAMENTO, QUE TIENE UN SCANNER DE RAYOS LASER (1) DELANTE DEL OVILLO DEL FILAMENTO. EN EL FOCO OPTICO DETRAS DEL OVILLO DEL FILAMENTO MEDIDO (2) SE ENCUENTRAN UNA OPTICA (3), POR EJEMPLO UNA LENTE O UN ESPEJO, ASI COMO UN FILTRO (4), PREFERENTEMENTE EN EL PLANO FOCAL DE LA OPTICA, QUE SIRVE PARA LA SUPRESION DE ECOS DE LA PARTE DE LUZ NO DISPERSADA, ASI COMO UN DETECTOR Y UN ANALIZADOR (5). EL FILTRO ES SOLAMENTE TRANSPARENTE PARA PARTES LIMITADAS DE LA IMAGEN DE DIFRACCION. EL DETECTOR SIRVE PARA MEDIR AL MISMO TIEMPO LAS INTENSIDADES EN VARIOS PUNTOS DE LA IMAGEN DE DIFRACCION. EN EL ANALIZADOR SE DETERMINAN LAS POSICIONES DEL FILAMENTO DEL RECORRIDO DE LA INTENSIDAD MEDIDA Y EL DIAMETRO DE LOS FILAMENTOS PARTIENDO DE LA RELACIONES DE INTENSIDAD MEDIDAS.
