Slow-Light Fiber-Bragg-Grating Strain Sensor With a 280- Resolution
Fiber Bragg gratings fi ber optics sensors
2013/8/7
We report a fiber strain sensor based on a single fiber Bragg grating (FBG) with a minimum detectable strain of 280 in the 20-kHz range. This breakthrough was made possible by operating th...
Characterization of strongly spun fibers with spin rate exceeding OFDR spatial resolution
spun fibers spin rate xceeding OFDR spatial resolution
2011/5/18
We describe an OFDR-based procedure to measure the spin of optical fibers with spin rates exceeding OFDR resolution. Fibers are twisted to locally unwind the spin and measurements are afterward reasse...
Resolution-enhanced ultrafast ADC using optical multi-period transfer functions of NOLMs
Ultrafast processes in fibers Fiber optics sensors
2010/6/9
We propose a resolution enhancement scheme using optical input/output multi-period transfer functions of NOLMs for ultrafast low-resolution ADCs. This scheme can provide a resolution of 8.8 ENOB by co...
High-resolution Refractive Index Sensing using Solid-core Photonic Crystal Fibers with High Index Infiltrations
High-resolution Refractive Index Sensing Solid-core Photonic Crystal Fibers
2008/8/4
We report the experimental demonstration of a refractive index sensor using scalable bandgap shift in two different structures of solid-core photonic crystal fibers. Resolution ~10 -7 refractive index...
Fiber-Optic Brillouin Distributed Discrimination of Strain and Temperature with 11-cm Spatial Resolution Using Correlation-Based Continuous-Wave Technique
Fiber-Optic Brillouin Distributed Discrimination Temperature Spatial Resolution Continuous-Wave Technique
2008/8/3
11-cm spatial-resolution distributed discrimination of strain and temperature is realized by measuring the Brillouin frequency shift and the birefringence from monitoring the dynamic grating spectrum ...
