Conformal fiber optic strain sensor |
摘要 |
A length of optical fiber is attached to a flexible base plate at two spaced apart locations. The portion of the fiber between the two points of connection is under a bias tension. An interferometer is formed in the tensioned portion of the optical fiber. The sensor is mounted to a surface and changes in interference patterns output by the interferometer are monitored to measure strain in the surface.
