Abstract

LA FRECUENCIA DE SUCESION DE IMPULSOS DE UN GENERADOR DE IMPULSOS OPTICOS CONSTITUIDO A PARTIR DE UN LASER (LAS) DE FIBRAS SE SINCRONIZA SOBRE UNA FRECUENCIA (FC) DE INTERVALO FIJA PREVIAMENTE DADA. LA SINCRONIZACION SE CONSIGUE A TRAVES DE UN MEDIO (M) PARA LA MODIFICACION DE LA LONGITUD DE VIA OPTICA DEL RESONADOR (RES) QUE SE CONTROLA POR MEDIO DE UNA SEÑAL DE REGULACION (RE) REGULADORA. COMO CRITERIO PARA LA SINCRONIZACION SE UTILIZA EL VALOR EFECTIVO DE UNA SEÑAL DE PERTURBACION SOBREPUESTA A LA LUZ DE SEÑALIZACION, QUE SUBE LA DESVIACION CORRESPONDIENTE DE LA FRECUENCIA DE SUCESION DE IMPULSOS A PARTIR DE LA FRECUENCIA DE INTERVALO. UNA PARTE DE LA SEÑAL (A) DE SALIDA DEL LASER (LAS) DE FIBRA SE TRANSFORMA DE FORMA OPTICA/ELECTRICA EN EL EQUIPO (RE) DE REGULACION Y SE DETERMINA LA SEÑAL ELECTRICA ASI OBTENIDA CON EL VALOR DE EFECTIVIDAD DE LA SEÑAL DE PERTURBACION MEDIANTE FILTRO Y RECTIFICADO. DESPUES DE LA AMPLIFICACION Y REGULACION, QUE TIENE LUGAR A CONTINUACION, SE GENERA LA SEÑAL DE REGULADOR PARA EL MEDIO (M) EN LA MODIFICACION DE LA LONGITUD DE VIA OPTICA. LA SEÑAL DE REGULACION SE MODULA ADICIONALMENTE CON UNA SEÑAL MODULADA DE FORMA QUE LA FRECUENCIA DE SUCESION DE IMPULSOS OSCILA SIEMPRE ALREDEDOR DE UN VALOR OPTIMO Y SE SINCRONIZA.
