Abstract
The optical fiber sensor is formed from an optical fiber having a light conducting optical fiber core, and a coating of cladding material, with a length of a sensing material matrix applied to the distal portion of the optical fiber core. The method involves removing a length of the cladding material from the distal portion of the optical fiber to expose a distal tip of the optical fiber core, applying a sensing material matrix to the exposed distal portion of the optical fiber core, and applying a coating of reflective material over the sensing material matrix.
