Abstract

UN DETECTOR PARA DETECTAR LAS DISTANCIAS A UN MEDIO Y/O LAS PROPIEDADES FISICAS DEL MISMO, QUE INCLUYE UN RECEPTACULO, AL MENOS UN PAR DE FIBRAS OPTICAS, CADA UNA DE LAS CUALES TIENE UNA PORCION FINAL DE ENTRADA Y UNA PORCION FINAL DE SALIDA, EN DONDE LA PORCION FINAL DE ENTRADA DE UNA PRIMERA FIBRA SE PUEDE CONECTAR A UNA FUENTE LUMINOSA Y LA PORCION FINAL DE SALIDA DE UNA SEGUNDA FIBRA SE PUEDE CONECTAR A UN DISPOSITIVO DE MEDICION DE LA INTENSIDAD DE LA LUZ. EL DETECTOR INCLUYE ADEMAS LAS PORCIONES FINALES DE ENTRADA Y DE SALIDA, EN DONDE CADA PORCION DE SALIDA DE LA PRIMERA FIBRA Y CADA PORCION FINAL DE ENTRADA DE LA SEGUNDA FIBRA TIENE UN EJE Y UN REBORDE, EN DONDE EL REBORDE ESTA CORTADO FORMANDO UN ANGULO {ZT} RESPECTO AL EJE Y SE ENCUENTRA COLOCADO DE FORMA ACOPLADA EN UN PLANO AL MENOS CERCA, Y QUE SE MIRAN, ENTRE SI, DE MODO QUE INCLUYA UN ANGULO {AL} ENTRE LOS EJES DEL MISMO. LA DISPOSICION ES TAL QUE, TRAS EL ACCIONAMIENTO, LA LUZ QUE EMERGE DE LA PORCION FINAL DE SALIDA DE LA PRIMERA FIBRA CHOCA CON UNA SUPERFICIE DE UN MEDIO, SEGUN UN ANGULO DE INCIDENCIA {BE}, Y EN DONDE {BE} = F({AL},{ZT}. TAMBIEN SE PRESENTA UN METODO PARA MEDIR AL MENOS INDIRECTAMENTE LAS DISTANCIAS A, Y/O LAS PROPIEDADES FISICAS DE, UN MEDIO.
