Abstract
ACELEROMETRO DE FIBRA OPTICA CON AMPLIA ANCHURA DE BANDA, QUE COMPRENDE UN MONITOR (24) PERCEPTOR DE VIBRACIONES QUE UTILIZA UN CRISTAL PIEZOELECTRICO (26) PARA MODULAR ELECTRICAMENTE LA FASE DE UN RAYO LASER USANDO UN MODULADOR DE FASE (28) QUE PRODUCE UN RAYO DE LUZ MODULADO EN FASE LINEALMENTE. UNA POLARIZACION DE CORRIENTE CONTINUA PUEDE SER PROPORCIONADA POR UNA BATERIA (60) MIENTRAS QUE UNA FOTOCELULA (64) PUEDE PROPORCIONAR LA POLARIZACION DE CORRIENTE CONTINUA JUNTO CON UNA SEÑAL DE CALIBRACION. LA SENSIBILIDAD DEL PERCEPTOR (24) SE PUEDE DUPLICAR HACIENDO PASAR EL RAYO DE LUZ POR DOS VECES POR EL PERCEPTOR (24) USANDO UN REFLECTOR (74). DIRIGIENDO LAS FIBRAS OPTICAS (20), (22) Y (31), QUE TRANSMITE UN RAYO DE REFERENCIA Y UN RAYO PERCEPTOR A LO LARGO DEL MISMO TRAYECTO FISICO, PUEDE ELIMINARSE EL RUIDO ORIGINADO POR LOS ESFUERZOS MECANICOS.
