Abstract A low-cost optical fibre sensor based on two cascaded balloon-like bent fibre (BBF) structures for simultaneous displacement and temperature measurement is reported. The sensor is fabricated by cascading two balloon-like bent single-mode fibres (SMFs) which with different bending radii, generating two separate interference dips within a limited wavelength range. The wavelength of the two interference dips exhibits different responses to external displacement and temperature variations, hence simultaneous measurement of displacement and temperature is realized. Experimental results show that the proposed optical fibre sensor achieves a displacement sensitivity of −318.8 pm/μm and a temperature sensitivity of 47.4 pm/°C. Taking advantage of its low-cost, ease of fabrication, and experimentally determined high sensitivity, the sensor in this investigation can be potentially applied in both displacement and temperature measurement fields.

基于两个级联气球状弯曲纤维结构的位移和温度同时测量
摘要 报道了一种基于两个级联气球状弯曲光纤 (BBF) 结构的低成本光纤传感器,用于同时测量位移和温度。该传感器是通过级联两个具有不同弯曲半径的气球状弯曲单模光纤 (SMF) 制造的,在有限的波长范围内产生两个独立的干涉下降。两个干涉倾角的波长对外界位移和温度变化表现出不同的响应,从而实现了位移和温度的同步测量。实验结果表明,所提出的光纤传感器的位移灵敏度为-318.8 pm/μm,温度灵敏度为47.4 pm/°C。利用其低成本、易于制造和实验确定的高灵敏度,
