Title:
OPTICAL FIBER STRAIN GAGE
Document Type and Number:
Japanese Patent JP2007212460
Kind Code:
A
Abstract:

To provide an optical fiber gage and a gage carrier.

The optical fiber gage is applied with a physical strain onto an optical fiber, and an axial tension of the fiber is changed thereby to change an optical characteristic propagated through the fiber. The gage carrier is provided with an advantage of a metal carrier handled and attached easily without worsening performance of the gage, and at least one part thereof is elastic related to expansion, compression or the both, along a longitudinal direction thereof, to change a distance between two points with the gage carrier attached to a test piece. The gage carrier fixes firmly the two independent fibers separated by a flexible member, in a specified embodiment. A fiber Bragg grating strain gage is also provided to monitor a peripheral situation and to measure a physical characteristic and a mechanical phenomenon.
