Vibration area localization and event recognition for
Using the cable as a vibration sensing medium, we design experiments to collect real-world vibration threat events.
Long distance distributed optical fiber vibration sensing and
Based on this, a distributed optical fiber vibration sensing and positioning scheme by combining distributed polarization state detection with cross-correlation analysis is further proposed.
Optic Cable Tracking and Positioning Method Based on
This paper makes the analysis of fiber optic cable tracking and positioning analysis based on distributed fiber vibration sensing.
Distributed Fiber Optic Vibration Sensing (DVS) System
Unlike traditional point-type vibration sensors, DVS realizes continuous, real-time vibration monitoring and positioning along the entire length of the fiber, covering distances up to 60km per channel.
CN110518968B
The invention relates to the technical fields of optical communication testing and optical fiber sensing, in particular to a device and a method for positioning optical cable vibration.
An Ameliorated Positioning Scheme for Optical Fiber Interferometer
To validate the effectiveness of the proposed positioning scheme, experiments were conducted to localize vibration events along a 101-km sensing fiber cable using an annular
