Fiber-optic ground settlement sensor based on low-coherent
A fiber-optic GS methodology was proposed by using a scanning low-coherent Michelson interferometer. One of the paths of the interferometer is formed by the liquid surface, and therefore the readout of

Design and investigation of a novel optic fiber sensor based on OTDR
In light of these challenges, we propose a novel fiber optic sensor that leverages the linear macro-bending loss principle, coupled with a spatial helical spring to monitor settlement deformations.
RAIL-MOUNTED OPTICAL FIBER SENSORS FOR
The Federal Railroad Administration (FRA) sponsored a research team from Oklahoma State University (OSU) to assess how well Optical Fiber Sensors (OFS), specifically Fiber Bragg Grating (FBG)
Optical fiber sensing monitoring device for soil settlement and
The present disclosure relates to the technical field of civil engineering monitoring equipment, and in particular, an optical fiber sensing monitoring device for soil settlement and a...
Optical-Fiber-Embedded Beam for Subgrade Distributed Settlement
As contact winding cannot be used for an optical fiber that is buried directly in the soil, uncoupling between the fiber and the soil can occur. Thus, an optical-fiber-embedded beam (OFEB)
Theory of application of fiber optics sensors to settlement monitoring
This theoretical result is used to show that existing smart fiber optics sensors can measure these settlements with resolution of tens of millimeters. Discussed are theoretical resolutions of settlement
Application of Distributed Optical Fiber Sensors for Monitoring
