Claims
- 1. An optical fiber sensor comprising:a tubing, an optical fiber residing inside the tubing, and a membrane attached to the tubing; and a plugging material located between said optical fiber and said tubing, wherein an air-tight cavity is formed by said plugging material in combination with said tubing and said optical fiber and said membrane, whereby the surface of said membrane becomes resilient due to the air-cushion effect of said air-tight cavity; wherein the surface of the membrane is non-planar, smooth, and taut.
- 2. The optical fiber sensor of claim 1, wherein the surface of the membrane is convex as viewed from outside of the tubing.
- 3. The optical fiber sensor of claim 1, wherein the surface of the membrane is spherical.
- 4. The optical fiber sensor of claim 1, wherein the surface of the membrane is conical.
- 5. The optical fiber sensor of claim 1, wherein the surface of the membrane is of a wedge shape.
- 6. The optical fiber sensor of claim 1, wherein said membrane is made of a partial surface of a whole spherical ball.
- 7. The optical fiber sensor of claim 6, wherein said spherical ball is solid.
- 8. The optical fiber sensor of claim 6, wherein said spherical ball is hollow.
