Abstract
There are described methods, systems, and computer-readable media for detecting events in a conduit. A first length of optical fiber, positioned alongside the conduit, is interrogated to obtain interferometric data from the first length of optical fiber. A second length of optical fiber, positioned alongside the conduit, is interrogated to obtain interferometric data from the second length of optical fiber. The interferometric data obtained from the first length of optical fiber is compared with the interferometric data obtained with the second length of optical fiber. Based on the comparison, whether an event has occurred in the conduit is determined.
Claims14
A method of detecting events in a conduit, comprising:
- interrogating a first length of optical fiber, positioned alongside the conduit, to obtain interferometric data from the first length of optical fiber;
- interrogating a second length of optical fiber, positioned alongside the conduit, to obtain interferometric data from the second length of optical fiber;
- comparing the interferometric data obtained from the first length of optical fiber with the interferometric data obtained from the second length of optical fiber;
- and
- determining, based on the comparison, whether an event has occurred in the conduit.
A system for detecting events in a conduit, comprising:
- a conduit;
- first and second lengths of optical fiber positioned alongside the conduit;
- an optical fiber interrogator configured to:
- interrogate the first length of optical fiber so as to obtain interferometric data therefrom;
- and
- interrogate the second length of optical fiber so as to obtain interferometric data therefrom;
- and
- one or more processors communicative with a memory having stored thereon computer program code configured when executed by the one or more processors to cause the one or more processors to perform a method comprising:
- comparing the interferometric data obtained from the first length of optical fiber with the interferometric data obtained from the second length of optical fiber;
- and
- determining, based on the comparison, whether an event has occurred in the conduit.
A computer-readable medium having stored thereon computer program code configured when executed by one or more processors to cause the one or more processors to perform a method comprising:
- obtaining interferometric data from a first length of length of optical fiber, wherein the first length of length of optical fiber is positioned alongside a conduit;
- obtaining interferometric data from a second length of optical fiber, wherein the second length of optical fiber is positioned alongside the conduit;
- comparing the interferometric data obtained from the first length of optical fiber with the interferometric data obtained from the second length of optical fiber;
- and
- determining, based on the comparison, whether an event has occurred in the conduit.
