Using micro-cantilever beam, the response frequency character of the Bragg fiber grating is studied in the experiments. Its responsed frequency width is 2.5 kHz and the experi mental fitting curve is given. The researches indicate that the shift average values of re flection wavelength scanning of Bragg fiber grating are very sensitive to the resonance frequen cy vn of the micro-cantilever beam.
