Enhanced signal-associated noise in a φ-otdr system

HIGHLIGHTS

  • who: . and colleagues from the École Polytechnique Fédérale de Lausanne, SCI-STI-LT Station, Lausanne, Switzerland have published the article: Enhanced signal-associated noise in a Φ-OTDR system, in the Journal: (JOURNAL)
  • what: The work is, therefore, utterly significant to the optical fiber sensing researchers who deal with such reflection-enhanced fibers for various distributed measurements. The frequency uncertainty (σf ) of the temperature measurement calculated from the traces for an arbitrary fiber distance of 40 m (shown in the inset of the upper figure of Fig 9) as well as the theoretical uncertainty . . .
