本文报道了用非高双折射光纤制作的长周期光纤光栅在测量横向应变双折射的基础上作为光纤负载传感器的一种新应用。横向应变灵敏度比以前报道的光纤布拉格光栅高800倍。
A novel application is reported of long-period fibre gratings produced in non-high-birefringence fibre as fibre optic load sensors based on the measurement of the transverse strain induced birefringence. A transverse strain sensitivity some 800 times higher than that previously reported for fibre Bragg gratings has been achieved.
