Abstract
EL SISTEMA CONSISTE EN UNA CABEZA TRANSDUCTORA (1), UN CANAL OPTICO (2) Y UNA UNIDAD DE GENERACION, DETECCION DE LUZ Y DE TRATAMIENTO Y PROCESADO DE SEÑAL (3). UNA VIBRACION MECANICA EN LA CABEZA TRANSDUCTORA ES REPRODUCIDA FIELMENTE (EN EL DOMINIO ELECTRICO) EN LA SALIDA DEL SISTEMA 3S1. ACELERACIONES O DESPLAZAMIENTOS EN LA CABEZA TRANSDUCTORA, GENERAN DESPLAZAMIENTOS EN UN TALLO DE FIBRA OPTICA Y MODULAN LA INTENSIDAD LUMINOSA QUE, COLECTADA DIFERENCIALMENTE POR DOS FIBRAS OPTICAS, SE ENVIA A TRAVES DEL CANAL OPTICO A LA UNIDAD DE DETECCION, ACONDICIONAMIENTO Y PROCESADO DE SEÑAL, LA CUAL REPRODUCE EN SU SALIDA LA ACELERACION O EL DESPLAZAMIENTO EN LA CABEZA TRANSDUCTORA. EL SISTEMA ES ESCALABLE, PUDIENDO MEDIR SIMULTANEAMENTE VIBRACIONES EN PUNTOS DIFERENTES. EL SISTEMA, SIN DESPRECIAR OTRAS APLICACIONES, MIDE ACELERACIONES DE BAJA Y MUY BAJA FRECUENCIA O DESPLAZAMIENTOS EN INSTALACIONES, ESTRUCTURAS, EQUIPOS Y COMPONENTES, TRABAJANDO EFICIENTEMENTE EN AMBIENTE ELECTRICA, MAGNETICA O ELECTROMAGNETICAMENTE CONTAMINADOS.
