Paper Abstract

A bent singlemode-multimode-singlemode (SMS) fiber structure based vibration sensor is proposed and developed. This sensor configuration is very simple and employs a bent SMS fiber structure and a narrow band optical source such as a laser. The vibration applied to the bent SMS fiber structure will change the bend radius and hence the intensity of the transmitted optical power will also vary. Experimental results show that the sensor can detect vibration frequencies over a broad range with good sensitivity, from hertz to a few kHz.
