Abstract:
An apparatus for estimating at least one parameter includes: a deformable member configured to deform in response to the at least one parameter; a housing surrounding at least a portion of an external surface of the deformable member to define an isolated region around the portion and an isolated surface of the deformable member; and at least one optical fiber sensor disposed on the isolated surface and held in an operable relationship with the isolated surface, the at least one optical fiber sensor configured to generate a signal in response to a deformation of the deformable member.
