Distributed optical pressure and temperature sensors
First Claim
1. A carrier for an optical fiber having a plurality of optical sensors located thereon, said carrier comprises:
- a sealed hollow body having a side wall, wherein the side wall is profiled at least one predetermined location to form a thin-walled section and wherein at least one optical sensor is directly attached to a surface of said thin-walled section, so that said thin-walled section flexes in response to a pressure difference across the thin-walled section and said pressure difference is sensed by said at least one optical sensor, wherein the sealed hollow body is a tube.

Abstract
Disclosed herein is a carrier for an optical fiber having a plurality of optical sensors located thereon. Such carrier can be a thick-walled capillary tube or other shapes. The carrier has a sealed hollow body with a side wall. The side wall is profiled at least one predetermined location to form a thin-walled section and at least one optical sensor is attached to said thin-walled section. As the thin-walled section flexes in response to a pressure difference across it, the pressure difference is sensed by the optical sensor. The carrier may also have a slot defined on its side wall to receive the optical fiber. A temperature optical sensor may also be provided adjacent to the pressure optical sensor.
