Low-Frequency Drift Compensation Method for Interferometry Fiber-Optic Vibration Sensing Using Sampling Matched Integral Fitting Difference
We demonstrate a low-frequency drift compensation method in interferometry fiber-optic vibration sensing system without any additional components and achieve 65.13 dB @ 10mHz phase noise floor suppression and 50.22 dB @ 1Hz SNR improvement.
