Abstract
EN UN GIROSCOPIO LASER, UNA MODULACION DE FASE NO RECIPROCA SE INTRODUCE ENTRE LOS HACES EN SENTIDO DE LAS AGUJAS DEL RELOJ (CW) Y LOS HACES EN SENTIDO EN CONTRA DE LAS AGUJAS DEL RELOJ (CCW) EN UN FRECUENCIA DE MODULACION (F). LOS HACES CW Y CCW SE COMBINAN SOBRE UN DETECTOR Y LA INTENSIDAD DE LA SALIDA SE OBSERVA EN LA FRECUENCIA FUNDAMENTAL (F) Y LOS ARMONICOS MAYORES (POR EJEMPLOS 2F, 4F). EN CADA FRECUENCIA, LA SEÑAL DETECTADA EN LA MISMA FRECUENCIA SE DEMODULA MEZCLANDOLA CON UNA SEÑAL DE REFERENCIA Y SE HACE PASAR LA FASE DE LA SEÑAL A TRAVES DE INCREMENTOS SUCESIVOS DE 90 (GRADOS) , CON LO QUE SE DETERMINA LOS COMPONENTES EN FASE Y DE CUADRATURA PARA CARA FRECUENCIA MONITORIZADA.
