invisensing : sensing beyond and beyond sensing
The elegant technique of distributed fiber sensing offers unprecedented features for its ability of monitoring physical and chemical parameters with spatial continuity along the sensing fiber cable. The offered solution is especially attractive in the following scenarios:
(1) Sensing along a very long distance with position-resolved information required, such as health condition monitoring of railway lines, leakage detection in pipelines, etc.;
(2) Sensing areas not easily accessible by other sensors, for instance, in drilling wells.
We build interrogators for distributed acoustic sensor (DAS) customizable based on the user’s requirements. We also provide DAS interrogators capable of retrieving vectorial acoustic field via a polarization-resolved DAS and close collaborations with sensing cable manufacturers.
