Guide Distributed Acoustic Sensing | Bandweaver
Distributed acoustic sensing systems (DAS) are fiber optic based optoelectronic instruments which measure acoustic interactions along the length of a fiber optic sensing cable.
Guide Distributed acoustic sensing
In DAS, the optical fiber cable becomes the sensing element and measurements are made, and in part processed, using an attached optoelectronic device. Such a system allows acoustic frequency strain
