Patent ID: 8151648

Claim:
A surface-mountable ultra-miniature fiber-optic pressure sensor system, comprising: at least one sensing head, said at least one sensing head being formed on an optical fiber having an optical guide channel defined within sidewalls and extending between an input end and a tip end of said optical fiber, wherein said tip end of said optical fiber is formed with an end surface angled substantially at 45° relative to an optical axis of said optical guide channel of said optical fiber and covered with a first reflective layer, wherein said reflective angled end surface redirects light traveling along said optical guide channel from said input end toward said tip end to impinge on said sidewall of said optical fiber at a predetermined location thereof; and a Fabry-Perot cavity structure formed at said predetermined location at said sidewalls of said optical fiber; wherein optical characteristics of an optical output signal emanating from the input end of said optical fiber correspond to a pressure applied to said Fabry-Perot cavity structure.
