摘　　要：提出一种基于FBG(Fiber Bragg Grating)光纤光栅传感器实现皮革弹性测量中温度、因温度变化引起的皮革纤维受力变形长度变化量和拉伸力引起的皮革纤维受力变形长度变化量三个参数被测量。采用用宽夹子把皮革样品两端固定好,并把一个FBG1传感器固定在夹子上,并在沿皮革样品发生形变方向放置FBG2传感器来解决皮革弹性变形和温度相互交叉感染问题;同时采用镀层FBG来提高FBG传感器的灵敏度。实验表明,三个参数能被精确和同时测量;并且FBG传感器灵敏度也被提高了8～13倍。A three-parameters measurement system based on Fiber Bragg Grating（FBG） is presented.It can detect the temperature and the leather fiber length which is caused by the temperature or the tensile strength.First the both side of the leather samples is fixed with two wide clips.Then one FBG sensor is fixed in the one of the wide clips,and the second FBG sensor is placed in parallel with the direction of the leather samples deformed.It is adopted to resolve the cross-sensitivities between the temperature and tensile strength,also the material-coated FBG was adopted to increase the FBGs sensitivities.As indicated by the experiment,the three parameters can be measured in accuracy and real-time,and the FBGs sensitivities can be improved to 8~13 times.
