Abstract

PARA LOGRAR EN UN GIROSCOPO DE OPTICA DE FIBRAS CON UN ACOPLADOR 3X3 (6) DISPUESTO ENTRE UNA FUENTE DE LUZ (L) Y UNA BOBINA DE FIBRA MONOMODO (2), QUE ACOPLA LUZ NO POLARIZADA EN LOS EXTREMOS DE LA BOBINA Y, AL MENOS, UN ELEMENTO FOTODETECTOR (D2, D3) ASIGNADO AL ACOPLADOR PARA LA GENERACION DE UNA SEÑAL DE SALIDA CORRESPONDIENTE A LA INTENSIDAD DE LUZ TRANSMITIDA POR EL ACOPLADOR, UN CONTRASTE MAXIMO DE LA SEÑAL DE INTERFERENCIA A EVALUAR, SE HA DISPUESTO SEGUN LA INVENCION, ENTRE LOS PUNTOS DE CONEXION DE LADO DE LA BOBINA (A2, A3) DEL ACOPLADOR 3X3 (6), A LO LARGO DEL RAMAL DE FIBRA MONOMODO (4) QUE FORMA LA BOBINA, AL MENOS UN ELEMENTO DE AJUSTE DEL CONTRASTE EN FORMA DE UN FIBRA GIRATORIA POR POLARIZACION, CUYO ANGULO GIRATORIO DE POLARIZACION ESTA AJUSTADO DE TAL MANERA, QUE LA SEÑAL DE SALIDA DEL ELEMENTO FOTODETECTOR ES MINIMA CUANDO EL GIROSCOPO ESTA EN REPOSO.
