A quasi-distributed temperature sensor interrogated by optical frequency-domain reflectometer
(IOP Publishing, 2011-11)
This paper presents the analysis of a quasi-distributed sensor based on the concatenation of identical low-reflective fiber Bragg gratings. We experimentally demonstrated a temperature sensor using ten cascaded gratings ...
Analysis and suppression of nonlinear frequency modulation in an optical frequency-domain reflectometer
(Optical Society of America, 2009-03)
A new method for monitoring the nonlinearities perturbing the optical frequency sweep in high speed tunable laser sources is presented. The swept-frequency monitoring system comprises a Mach-Zehnder interferometer and ...
