Diagnostic systems of optical fiber coil sensors for structural health monitoring
First Claim
1. A diagnostic system for monitoring structural health conditions of an object, comprising:
- at least one optical fiber sensor including;
a rolled optical fiber cable operative to generate a frequency shift of a light signal passing therethrough, the frequency shift being commensurate with vibration of the object; and
a coating layer applied to the rolled optical cable; and
an electronic module operative to send an input light signal to the optical fiber sensor, to receive a sensor signal from the optical fiber sensor, and to process the sensor signal.

Abstract
Devices for monitoring structural health conditions of host structures. A device includes at least one optical fiber sensor and an electronic module. The optical fiber sensor includes a rolled optical fiber cable operative to generate a frequency shift of a light signal passing therethrough and a coating layer applied to the rolled optical cable. The frequency shift is commensurate with vibration of the host structure. The electronic module sends an input light signal to the optical fiber sensor, receives a sensor signal from the optical fiber sensor, and processes the sensor signal.
