光纤布拉格光栅传感
Fiber Bragg Grating SensingA method of optical fiber sensing that uses the periodic modulation of the refractive index in the core of a single-mode optical fiber to create a wavelength-specific reflector. It is used to measure physical quantities such as strain, temperature, and vibration by detecting the shift in the reflected wavelength. / 一种光纤传感方法，利用单模光纤纤芯中折射率的周期性调制来创建波长特定的反射器。它通过检测反射波长的偏移来测量应变、温度和振动等物理量。
