Abstract
A bend singlemode-multimode-singlemode (SMS) fibre structure based vibration sensor is proposed and developed. This sensor configuration is very simple and employs a bend SMS fibre structure and a broadband optical source. The vibration applied to the bend SMS fibre 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 both vibration frequencies and amplitudes over a broad range with good sensitivity, from a hertz to 12 kHz. © 2014 Elsevier Ltd.
