In the practical phase generated carrier (PGC) demodulation outputs, the direct current (DC) drift can distort the demodulation results.
在实际的相位生成载波(简称PGC)解调输出中，直流漂移会使解调结果产生失真。
The system is based on Michelson interferometer. It USES a fiber laser with narrow linewidth as light source, and adopts homodyne demodulation with phase generated carrier scheme to restore signal.
