Keywords: monitoring of extended objects, distributed acoustic sensing, DAS, DAS application in geophysics
Аnnotation: Modern monitoring systems of infrastructural objects, stretched long distances, are based on non-contact meth-ods. Distributed acoustic sensing (DAS) is a technology which has been developing rapidly in recent years due to its high channel density and real-time operation. DAS can have many applications, including finding new oil and gas reserves and monitoring seismological activity. In the field of monitoring of extended objects, DAS has al-ready been used for a number of years. These systems are similar to those which are used in geophysics. Each system consists of a very long fiber optic cable and an interrogator connected to the end of the cable. Often the cable is not attached to the structure, but is buried at a short distance from it. We propose to discuss the possibility of using the data obtained from such monitoring for research in geophysics. The data can be used in geo-physics without connecting any additional equipment.
