English Abstract

During the design of a practical interferometric fiber-optic sensor, one of the key problems is to compensate phase random shifting and eliminate frequency doubling caused by strong signal. In this paper a simple but pratical method was presented, which makes use of piezoelectric ceramics (PZT's) piezoelectricity to modulate the fiber-optic sensor. The feasibility of the method was theoretically analyzed in detail, in terms of the detection of weak signal and strong signal respectively and well proved by experiments. The experimental result proves that the method presented in the paper is a satisfying one to resolve the problem well.
