Abstract
DISPOSITIVO DE MEDIDA DE CORRIENTE MAGNETO-OPTICO QUE INCLUYE UNA DISPOSICION DE LENTES DE COLIMACION [FIG. 2C, (34, 38)] PARA LA CONCENTRACION DE UNA SEÑAL DE LUZ EN UN RAYO PARALELO DE LUZ, CUYO RAYO DE LUZ, CUANDO ESTA POLARIZADO SE COMUNICA A TRAVES DE UN ROTOR DE FARADAY [FIG. 3, (10)] QUE SE DISPONE CERCA RODEANDO LA LINEA DE TRANSMISION EN LA QUE SE DESEA MEDIR EL FLUJO DE CORRIENTE. LOS ELEMENTOS LENTES DE COLIMACION SE FORMAN A PARTIR DE UN SEGMENTO DE UNA LENTE PARABOLICA [FIG. 3, (38, 42)] Y UN ELEMENTO SEPARADOR DE LENTES [FIG. 3, (34, 46)] QUE TIENE UNA SUPERFICIE PLANA FORMADA MEDIANTE UN BORDE OPUESTO DE LA SUPERFICIE PARABOLICA, ESTA SUPERFICIE PLANA SE EXTIENDE HASTA LA LONGITUD FOCAL DE LA SUPERFICIE PARABOLICA. LOS ELEMENTOS LENTES DE COLIMACION [FIG. 3, (34, 38)] SE CONSTRUYEN CON LA FORMA DE UNA CONFIGURACION MONOLITICA Y DESPUES SE ASEGURAN JUNTO CON EL ELEMENTO DE POLARIZACION [FIG. 3, (40, 44)] AL ROTOR DE FARADAY [FIG. 3, (10)] DE FORMA QUE ASI SE ELIMINE TODAS LAS INTERFASES AIRE-A-VIDRIO.
