Abstract

UN APARATO PARA EMITIR Y RECIBIR LA LUZ QUE CONSTA DE UN EMISOR, COMPUESTO DE UNA FUENTE DE LUZ (5) Y UN ESPEJO CONCAVO (7), Y UN RECEPTOR QUE RECIBE LA LUZ DEL EMISOR Y QUE ESTA CONECTADO A UN EQUIPO DE ANALISIS (3). ADEMAS, EL RECEPTOR CONSTA DE UN ESPEJO CONCAVO (9) QUE ESTA DISPUESTO DETRAS DEL ESPEJO (7) DEL EMISOR Y CUYO DIAMETRO ES MAYOR QUE EL DEL ESPEJO (7) DEL EMISOR Y CUYO FOCO ESTA LOCALIZADO FRENTE A LA FUENTE DE LUZ (5). EN EL FOCO DEL ESPEJO (9) SE SITUA UN EXTREMO DE UNA FIBRA OPTICA (19) PARA LA TRANSMISION DE LA LUZ RECIBIDA AL EQUIPO DE ANALISIS (3). TAMBIEN EL APARATO CONSTA DE UNA UNIDAD RETRO-REFLECTORA (17) PARA REFLEJAR LA LUZ DEL EMISOR AL RECEPTOR, Y UN ELEMENTO DE ESCUDO MOVIBLE (11) QUE ESTA COLOCADO ENTRE LA FUENTE DE LUZ (5) Y LA FIBRA OPTICA (19) Y QUE IMPIDE, EN UNA PRIMERA POSICION, QUE LA LUZ DE LA FUENTE DE LUZ ALCANCE LA FIBRA OPTICA DIRECTAMENTE, Y PERMITE, EN UNA SEGUNDA POSICION, QUE LA LUZ DE LA FUENTE DE LUZ LLEGUE DIRECTAMENTE A LA FIBRA OPTICA.
