Performance of Seismic Observations by DAS Technology in Different Environments
摘要
Distributed Acoustic Sensing (DAS) uses similar equipment and primary data processing algorithms for various tasks in geophysics. DAS has wide frequency and dynamic ranges. This allows for research in the field of seismology, volcanology, marine geophysics, glaciology, engineering geophysics, etc. Specially laid fiber-optic cables, dark fibers of telecommunication lines and data obtained from monitoring systems of extended objects can be used for such work. Why does the DAS technology advance in geophisics so slowly? This article tries to answer this question.
