Norway DAS Fiber Optic Sensor
Sensnet Analytics AS, created at the Norwegian University of Science and Technology (NTNU), is developing distributed acoustic sensing (DAS) systems that transform ordinary fiber-optic cables into networks of sensors. The use of fiber technology is rapidly evolving, and at NORSAR, we leverage our extensive expertise in vibration. The OptoDAS interrogator is using a unique interrogation technique providing low-noise and long-range quantitative phase measurements in single mode optical fibers. The conventional technique for measuring the reflected DAS signal from the fiber is pulsed interrogation where short pulses are. DAS technology, ideal for long-distance monitoring of infrastructure like powerlines and underwater cables, ensures grid reliability through real-time monitoring, fault detection, and security surveillance. Fiber cables along railways enable DAS technology, monitoring trains for safety, security. If a section of the optical fibre is subjected to strain, the propagating light will experience an optical phase delay. By analyzing the back-reflected signal one can extract the optical phase modulations induced along the optical fibre.

Fiber Optic Sensor Roughness
In order to measure inner surface roughness of small holes nondestructively, a new fiber optic sensor is researched and developed. A new method for the calculation of reflection light intensity is proposed. By numerically counting the amount of reflection light rays from a measured surface, the relationship between the reflection. A method of surface roughness measurement is disclosed which uses a fiber-optic probe having a sensor head constituted of a light-emitting fiber and multiple light-receiving fibers disposed coaxially with the light-emitting fiber. The flexible, contactless technology makes it possible to adapt the measuring systems to your individual requirements. Our roughness measuring station.
