摘要
A novel lateral force sensor based on a core-offset tilted fiber Bragg grating (TFBG) is proposed and experimentally demonstrated. The lateral force is determined by the differential reflected powers between the cladding mode and Bragg mode in the TFBG. The sensors respond monotonically with the lateral force increasing from 0 to 1.75 N. The sensitivity of such a core-offset TFBG sensor can be tailored by choosing different core-offset values. The simple differential power detection method makes the implementation of the sensor system cost-effective and free of the influence of environmental and system fluctuations. (C) 2010 Elsevier B.V.
