Journal ArticleDOI
High-resolution absolute frequency referenced fiber optic sensor for quasi-static strain sensing
Timothy T.-Y. Lam,Jong H. Chow,Daniel A. Shaddock,Ian C. M. Littler,Gianluca Gagliardi,Malcolm B. Gray,David E. McClelland +6 more
TL;DR: A quasi-static fiber optic strain sensing system capable of resolving signals below nanostrain from 20 mHz is presented, using a telecom-grade distributed feedback CW diode laser locked to a fiber Fabry-Perot sensor.
Journal ArticleDOI
Picometer level displacement metrology with digitally enhanced heterodyne interferometry.
Glenn de Vine,D. S. Rabeling,B. J. J. Slagmolen,Timothy T.-Y. Lam,Sheon Chua,Danielle M. R. Wuchenich,David E. McClelland,Daniel A. Shaddock +7 more
TL;DR: The first characterization of the technique's displacement sensitivity is presented, and the applicability of digitally enhanced heterodyne interferometry for lock acquisition of advanced gravitational wave detectors is discussed.
Journal ArticleDOI
Optical Fiber Sensing Based on Reflection Laser Spectroscopy
Gianluca Gagliardi,M. Salza,Pietro Ferraro,E. Chehura,Ralph P. Tatam,Tarun Kumar Gangopadhyay,Nicholas Ballard,Daniel Paz-Soldan,Jack A. Barnes,Hans-Peter Loock,Timothy T.-Y. Lam,Jong H. Chow,Paolo De Natale +12 more
TL;DR: An overview on high-resolution and fast interrogation of optical-fiber sensors relying on laser reflection spectroscopy is given and results on detection performances are presented.
Journal ArticleDOI
Weak-light phase tracking with a low cycle slip rate.
Samuel P. Francis,Timothy T.-Y. Lam,Kirk McKenzie,Andrew J. Sutton,R. L. Ward,David E. McClelland,Daniel A. Shaddock +6 more
TL;DR: A phase-locked loop to track changes in the phase of an optical signal that has been transmitted hundreds of kilometers between two spacecraft will enable a new class of missions, opening up new opportunities for space-based interferometry.
Journal ArticleDOI
Optical fiber three-axis accelerometer based on lasers locked to π phase-shifted Bragg gratings
Timothy T.-Y. Lam,Timothy T.-Y. Lam,Gianluca Gagliardi,M. Salza,Jong H. Chow,Paolo De Natale +5 more
TL;DR: In this article, a high-bandwidth, three-axis accelerometer developed with π phase-shifted fiber Bragg gratings is presented, where the gratings are inserted into a cantilever system and interrogated by three separate distributed-feedback diode lasers.
