Magnetic Optical FBG Sensors Using Optical Frequency-Domain Reflectometry
IEEE Transactions on Magnetics, 2019The optical frequency-domain reflectometry (OFDR) sensing system and signal processing method, which is based on the short-time Fourier transform, enable us to interrogate reflected wavelengths of fiber Bragg gratings (FBGs) and their relative position along the optical fiber with high spatial resolution.

Coherent optical frequency domain reflectometry for a 1000-km optical fiber
OFC '98. Optical Fiber Communication Conference and Exhibit. Technical Digest. Conference Edition. 1998 OSA Technical Digest Series Vol.2 (IEEE Cat. No.98CH36177), 2002Summary form only given. We demonstrated coherent optical frequency domain reflectometry (C-OFDR) for a long optical fiber transmission line. We simulated the measurement of a reflection at a one-way distance of >1000 km, and achieved a spatial resolution of about 130 m.

Monitoring optical fiber sensor networks by optical frequency-domain reflectometry
2012 Photonics Global Conference (PGC), 2012To improve the reliability that are very important for large-scale and long range all optical fiber sensor networks, monitoring optical fiber sensor networks is necessary. We proposed a novel method for monitoring optical fiber sensor networks using optical frequency-domain reflectometry (OFDR) which provides a narrow spatial resolution that enables us

Optical frequency domain reflectometry: principles and applications in fiber optic sensing
SPIE Proceedings, 2016Optical Frequency Domain Reflectometry (OFDR) is the basis of an emerging high-definition distributed fiber optic sensing (HD-FOS) technique that provides an unprecedented combination of resolution and sensitivity. OFDR employs swept laser interferometry to produce strain or temperature vs.

Digitally Enhanced Optical Frequency Domain Reflectometry with Long Measurement Range
Optical Fiber Communication Conference, 2015A digitally enhanced optical frequency domain reflectometry technique is proposed, in which the frequency-to-distance mapping is realized in digital domain. A spatial resolution of 1 m over 56 km was obtained in demonstrational experiments.

Time-domain optical reflectometry measurements using a frequency comb interferometer
Applied Optics, 2010We characterize the temporal response of fiber-optic components using a fiber-based frequency comb interferometer; measurements are compared and validated against a commercial instrument. The main advantage of the instrument lies in the absence of moving parts or a tunable laser, leading to very fast scanning.
