摘要：
A FBG sensor interrogation method for measuring applications requiring a wide wavelength range and a high rate interrogation is presented. An optical intensity transfer with a cosine-like shape is obtained by a fiber interferometer, which is periodically changed to a sine-like transfer by a phase modulator. The FBG sensor reflected light, after propagated through the interferometer, is detected. A tracking algorithm is used for determining the central wavelength of the FBG sensor. An analysis of the involved systematic measuring error is carried out which illustrates the method feasibility.
