Dynamic measurements of 1000 microstrains using chirped-pulse phase-sensitive optical time-domain reflectometry

This work demonstrates the capabilities of Chirped pulse, phase-sensitive optical time domain reflectometry (CP-PhiOTDR) to measure large dynamic strains. Benefitting from the use of incoherent detection and single shot measurements, this technique can sample the fiber under test at rates limited on...

Benefitting from the use of incoherent detection and single shot measurements, this technique can sample the fiber under test at rates limited only by the fiber length.
