Influence of the laser frequency drift in phase-sensitive optical time-domain reflectometry
A. A. Zhirnov, K. V. Stepanov, A. O. Chernutsky +5
The influence of the laser frequency drift on the operation of phase-sensitive optical time-domain reflectometry (-OTDR) systems is considered. Theoretical results based on a ne…
