WebDec 3, 2024 · Abstract: In this article, fast measurement of Brillouin optical time-domain reflectometry (BOTDR) based on a linearly frequency modulated (LFM) pulse and a digital matched filter is studied theoretically and demonstrated experimentally. WebJan 20, 2024 · Aiming at low stability and high harmonic distortion of the traditional phase-generated carrier (PGC) demodulation algorithm, we propose a modified demodulation algorithm for distributed strain sensing in phase-sensitive optical frequency domain reflectometry (OFDR). The proposed algorithm combines the arctangent function and …
