Comparison of Amplitude-Frequency Response Characteristics between DCM and Arctan Algorithms in Φ-OTDR

In phase-sensitive optical time-domain reflectometry (ϕ-OTDR) systems, DCM and Arctan demodulation algorithms are typically used to recover the information on vibration events along the fiber. The amplitude-frequency response characteristics of the DCM and Arctan algorithms are investigated and comp...
