Abstract
The optical fiber sensing system is provided. The optical fiber sensing system comprises an optical fiber measuring module, a floating module, and a containing structure. The floating module disposed in the containing structure has a plurality of floating units. Each floating unit has a mass element and a vibration absorbing structure. It is adapted to apply appropriate tensile force to the optical fiber measuring module by adjusting counterweight of the quality bodies. The vibrating influence to the optical fiber measuring system would be reduced through the vibration absorbing structure.
Claims13
An optical fiber sensing system, comprising:
- an optical fiber measuring module having a first optical fiber extension segment and a first sensing segment, the first sensing segment being formed on the first optical fiber extension segment;
- a floating module providing tensile force on the first sensing segment, and having:
- a central connector being connected to a first end of the first optical fiber extension segment;
- and
- a plurality of floating units contacting and surrounding the central connector, wherein each of the floating units has a vibration absorbing structure and a mass element;
- and
- a containing structure having a container for accommodating a fluid, wherein the fluid provides buoyant force to the floating module when the floating module is disposed into the fluid;
- wherein when an input signal is transmitted to the first sensing segment, a first output signal is generated after the input signal is processed by the first sensing segment, and the tensile force applied to the first sensing segment changes and the first output signal fluctuates accordingly with variation of the buoyant force on the floating module, and wherein a ratio of a density of the floating module to a density of the fluid is approximately 1.
