The wavelength demodulation of Fiber Bragg Grating(FBG) is one of the critical technologies and the research hotspot of fiber optical sensing.This paper presents a wavelength demodulation method based on FBG reflect filter technology,by using Acoustic Optic Tunable Filter(AOTF) to dynamically scan the reflected spectrum.The theoretical deducing and analysis of the system are introduced in detail.With entire fiber-optical structure and using computer for data processing,the wavelength… CONTINUE READING
