Monitoring the deformation behavior of an immersed tunnel with Distributed Optical Fiber Sensor (DOFS)

Sensing fiber selection for point displacement measuring with distributed optic fiber sensor

Distributed optical fiber sensors (DOFS) allow for distributed strain sensing and can be installed to function as extensometers for measuring point-displacements. This paper discusses the metrics of optimal sensing fiber selection for point-displacement measuring. Key metrics include the physical structure, mechanical parameters and light...
