摘要
我们提出并演示了一种用于倾斜光纤光栅传感器双波长差分检测的参考方案，该方案补偿了激光二极管波长的漂移和动态啁啾，从而获得了40 fm rms的稳定性，并且检测的折射率变化极限为3 \ × 10 ^{-6}$。
Measurement of Tilted Fiber Bragg Grating Sensors with Femtometer Resolution Using Dual-Wavelength Differential Detection
We propose and demonstrate a referencing scheme for dual-wavelength differential detection of tilted fiber Bragg grating sensors that compensates for drift in the laser diode wavelength and dynamic chirp, and results in 40 fm rms stability, and a refractive index change limit of detection of $3 \times 10 ^{-6}$.
