Patent number: 11860028Abstract: A vibration detection method is presented to accurately detect vibration physically applied to an optical fiber, using a simple determination reference. In a vibration detection method, scattered light of a given target segment of a measurement target fiber is indicated by vectors of an in-phase component and a quadrature component, and a triangular shape constituted by a near-end-side vector of the target segment and a far-end-side vector is used as a physical amount to be tracked. That is, it is determined whether or not there is vibration based on a change in shape of the triangular shape with respect to a reference state. This is a detection method in which DAS-I and DAS-P are combined, a simple determination reference such as shape change of a triangular shape is employed, and overlooking of vibration detection can be reduced.Type: GrantFiled: January 22, 2020Date of Patent: January 2, 2024Assignee: NIPPON TELEGRAPH AND TELEPHONE CORPORATIONInventors: Yoshifumi Wakisaka, Daisuke Iida, Keiji Okamoto, Hiroyuki Oshida
