High-reflectivity-resolution coherent optical frequency domain reflectometry using optical frequency comb source and tunable delay line.
We propose a high-reflectivity-resolution coherent optical frequency domain reflectometry (OFDR) with a novel scheme of delay shift averaging (DSAV) by using an optical frequency comb source and a tunable delay line to suppress the fading noise. We show theoretically and experimentally that the novel DSAV scheme is equivalent, in realizing a high reflectivity resolution, to our previously repor...
متن کاملHigh resolution optical frequency domain reflectometry for characterization of components and assemblies.
We describe a technique for polarization sensitive optical frequency domain reflectometry (OFDR) that achieves 22 micrometer two-point spatial resolution over 35 meters of optical length with -97 dB sensitivity in a single measurement taking only seconds. We demonstrate OFDR's versatility in both time- and frequency-domain metrology by analyzing a fiber Bragg grating (FBG) in both the spectral ...
متن کاملDistributed Rayleigh scatter dynamic strain sensing above the scan rate with optical frequency domain reflectometry
Luna recently demonstrated a novel optical phase-based algorithm for removing the adverse effects of fiber motion at frequencies far above the scan rate on high-resolution measurements of Rayleigh scatter using Optical Frequency Domain Reflectometry (OFDR) for static strain and temperature measurements. By comparing dynamic OFDR Rayleigh scatter measurements to a static reference, it is possibl...
متن کاملHigh-resolution multicomponent distributed acoustic sensing
Distributed acoustic sensing (DAS) uses an optical fiber together with an interrogator unit to perform strain measurements. The usage of DAS in geophysics is attractive due to its dense spatial sampling and low operation cost if the optical fiber is freely accessible. In the borehole environment, optical fibers for DAS are often readily available as a part of other sensing tools, such as for te...
متن کاملHigh Frequency Distributed Optical Fibre Dynamic Strain Sensing: A Review
The concept of using an optical fibre to map dynamic perturbations along the sensing fibre was first proposed by Taylor et al. (Taylor 1993) in 1993 and later demonstrated by his team in 2005 (Juarez 2005). The proposed sensor was only capable of detecting the dynamic perturbations along the sensing fibre by monitoring the changes in the pattern of the backscattered coherent Rayleigh noise (CRN...
