Abstract:A new optic fiber sensing and measuring system is established to measure small vibration displacement by using Erbium-Doped fiber linear laser.The method of fringe counting is applied to analyze SMI signal.A good linear relationship between the slaving voltage and vibration amplitude of loudspeaker is found.The experimental device has the advantage of being simple in structure and low in cost.The experimental result shows that the method of using this sensing system to measure vibration displacement is simple and fast,with the output signal quite stable. 更多
