Fiber optic displacement sensor using fiber optic coil |
摘要 |
A fiber optic microbend sensor employs a resilient coil (12) with an optical fiber (10) positioned therein. The coil (12) has a predetermined length and pitch. An optical signal is applied to the optical fiber (10) with the coil (12) interrogating a parameter. Any movement of the coil (12) modulates the optical signal transmitted along the optical fiber (10). Detecting means (32) measures the modulations of the optical signal for characterization of the parameter.
