It has been observed that when the multi-frequency Raman scattering process is pumped by two frequency chirped pulses in the transient regime, the anti-Stokes orders are spectrally broadened on the lower-frequency side, causing each of the orders to have...

As a fully distributed sensor, the phase-sensitive optical time domain reflectometer (f-OTDR) has attracted remarkable attention in real-time vibration detection. We present a dual-channel f-OTDR (DC-f-OTDR), formed by two single-channel f-OTDRs (SC-f-OT...
