Abstract

SISTEMA MAGNETOOPTICO PARA MEDIR LA VELOCIDAD ANGULAR DE UN EJE. DE LOS QUE MODIFICAN LA TRANSMISION POR REFLEXION DE UN HAZ DE LUZ QUE SE PROPAGA DESDE UN ELEMENTO EMISOR DE LUZ (11) A OTRO ELEMENTO RECEPTOR DE LUZ (12) SIN QUE EXISTA INTERACCION OPTICA ENTRE EL HAZ DE LUZ Y EL EJE GIRATORIO; QUE CUENTA CON UN IMAN PROVISTO DE UN TALADRO CENTRAL EN EL QUE SE UBICA UN SENSOR DE CAMPO MAGNETICO (6) EN EL QUE SE MODULA LA INTENSIDAD DEL HAZ DE LUZ CADA VEZ QUE SE PRODUCE EL PASO DE UN DIENTE DE UN DISCO DENTADO UNIDO AL EJE GIRATORIO, FRENTE AL IMAN (10). EL SENSOR DE CAMPO MAGNETICO (6) CUENTA, TRAS UN POLARIZADOR (2), CON UNA SUPERFICIE PARCIALMENTE REFLECTANTE (3) Y OTRA TOTALMENTE REFLECTANTE (5) ENTRE LAS QUE SE DISPONE UN ROTADOR DE FARADAY (4) CON LO QUE PARTE DE LA AMPLITUD, E0 DEL HAZ DE LUZ QUE INCIDE SOBRE LA SUPERFICIE PARCIALMENTE REFLECTANTE SE REFLEJA, Y EL RESTO SE TRANSMITE A TRAVES DEL ROTADOR DE FARADAY (4) REFLEJANDOSE EN SU TOTALIDAD EN LA SUPERFICIE TOTALMENTE REFLECTANTE (5), INCIDIENDO DE NUEVO EN LA SUPERFICIE PARCIALMENTE REFLECTANTE (3) QUE A SU VEZ REFLEJA PARTE DE LA AMPLITUD QUE SE TRANSMITE HACIA EL ROTADOR DE FARADAY (4) Y EL RESTO, E0, SE TRANSMITE A TRAVES DEL POLARIZADOR (2) HACIA LA FIBRA OPTICA (1); REPITIENDOSE EL PROCESO SUCESIVAMENTE DE TAL MANERA QUE SE AMPLIFICA EL ANGULO DE ROTACION DEL PLANO DE POLARIZACION DEL HAZ DE LUZ EN PRESENCIA DE UN CAMPO MAGNETICO.
