摘 要：The phase generated carrier（PGC） modulation-demodulation technique is the main demodulation technique for fiber interferometric *** are two methods to realize PGC *** method is inner modulation,and the other is external ***,there is less study on the PGC external modulation than the PGC inner *** this paper,we focus on the PGC external modulation to analyze its *** experiment results indicate that the external demodulation performs ***,its cost is much lower than that of inner modulation.
