本文报道了一种光纤光栅激光应变传感系统，在7 kHz频率下，其均方根应变分辨率为5.6 × 10 ~（-1）/sup ~（14）/Hz。干涉读出技术用于以高分辨率确定激光器中应变引起的波长偏移。
A fibre Bragg grating based laser sensor system with an RMS strain resolution of 5.6*10/sup 14// square root Hz at 7 kHz is reported. An interferometric readout technique is used to determine strain induced wavelength shifts in the laser with high resolution.
