Abstract

EL APARATO (10) COMPRENDE UN IMPULSOR DE LASER (16) QUE RECIBE SEÑALES DE ENTRADA ANALOGICAS Y DIGITALES DE BAJA Y ALTA VELOCIDAD (12, 14), Y POLARIZA Y MODULA EL DIODO DE LASER (22) . EL IMPULSOR DE LASER (16) RECIBE Y RESPONDE A LA ENTRADA DE UN CIRCUITO DE REALIMENTACION (36, 38), QUE COMPRENDE UNA PARTE DE CONTROL DE ENERGIA MEDIA (36), Y UNA PARTE DE CONTROL DE ENERGIA DE MODULACION (38). LA PARTE DE CONTROL DE ENERGIA MEDIA (36) DEL CIRCUITO DE REALIMENTACION DETERMINA GENERALMENTE EL COMPONENTE CC DE LA ENTRADA DE DIODO LASER, Y LO COMPARA LA CON UNA MEDIA DE REFERENCIA. LA PARTE DE CONTROL DE ENERGIA DE MODULACION (38) DEL CIRCUITO DE REALIMENTACION DETERMINA GENERALMENTE LOS PICOS MAXIMOS Y MINIMOS EN LA SALIDA DE DIODO D LASER, TOMA SU MEDIA Y COMPARA LA MEDIA CON EL COMPONENTE CC DE LA SALIDA LASER DE LA PARTE DE CONTROL DE ENERGIA MEDIA (36). EL DIODO LASER (22) ES IMPULSADO ENTONCES POR EL IMPULSOR LASER (16) EN RESPUESTA A LAS COMPARACIONES.
