A novel method is proposed to demodulate the output of Brillouin optical correlation domain analysis by using an analog signal processing unit free from the update rate limitation of the conventional method. The distributed Brillouin interaction per pump-probe frequency offset is continuously recorded during linearly sweeping the sensing positions. In experiment, we realize ~20-Hz distributed sensing...
We demonstrate a one-end-access high-speed distributed strain sensing with high spatial resolution in optical fibers based on Brillouin optical correlation-domain reflectometry. In this work, Brillouin frequency shifts (BFSs) of a 3- cm fiber section are measured with 13- mm spatial resolution and 50- Hz sampling rate. To our knowledge, this spatial resolution is the best result ever reported in Brillouin...
