PATCH TYPE OPTICAL FIBER SENSOR

摘要

In a patch type optical fiber sensor, an optical fiber (2) has at its part a fiber Bragg grating (3) and that part is fixed to a film (4) serving as a base to form a film-like detecting element. Opposite ends of that part are connected to optical cord (1) to protect the film-like detecting element The detecting element is bonded to an object (9) to be detected by bonding agent or by welding.
