Abstract: Conventional chirped-pulse (CP) phase-sensitive optical time-domain reflectometry (CP φ-OTDR) allows the interrogation of tens of kilometers of optical fiber with high accuracies of ...
Abstract: In this paper, we proposed a kind of novel optical time-domain reflectometer (OTDR) which employed the linear frequency modulation (LFM), the fractional Fourier transform (FrFT), and ...
