Abstract
SISTEMA MAGNETO-OPTICO DE MEDICION DE LA VELOCIDAD ANGULAR DE UN EJE. DE LOS QUE MODIFICAN LA TRANSMISION DIRECTA O POR REFLEXION DE LUZ QUE SE PROPAGA DESDE UN EMISOR (2) A OTRO RECEPTOR (3) SIN INTERACCION OPTICA ENTRE EL HAZ DE LUZ Y EL EJE GIRATORIO, NI ELEMENTO MOVIL ACCIONADO POR DICHO EJE GIRATORIO. LA MODIFICACION DE LA LUZ SE REALIZA VARIANDO EL ESTADO DE POLARIZACION DEL HAZ DE LUZ EN EL INTERIOR DE UN SENSOR DE CAMPO MAGNETICO (14), DISPUESTO ENTRE EMISOR (2) Y RECEPTOR (3), POR LA ACCION DE UN CAMPO MAGNETICO MODULADO POR EL GIRO DE UN EJE CUYA VELOCIDAD ANGULAR SE DESEA MEDIR. LA MEDIDA SE REALIZA DISPONIENDO CONCENTRICAMENTE CON EL EJE UN DISCO DE MATERIAL FERROMAGNETICO (16) CON VARIOS ORIFICIOS CON ELEMENTOS FERROMAGNETICOS (18) QUE DETERMINAN UN CIRCULO CONCENTRICO. EL DISCO (16) CUENTA, EN UN LATERAL, CON UN GENERADOR DE CAMPO MAGNETICO (15) Y EN EL OTRO CON UN SENSOR (14) ENFRENTADO A AQUEL.
