Again in Sensors!

The article presents a new approach to monitor displacements and strains in Glass Fiber Reinforced Polymer (GFRP) collectors and pipelines using DFOS. Sensing fibres were installed over the circumference of a composite pipe, both on the internal and external surfaces. Analysis of measured strain profiles allowed for calculating the actual displacements (shape) of the structure using the trapezoidal method known from our 3DSensor.
