Design of Fiber Bragg Grating Demodulation System Based on DSP

摘要：

Because the traditional demodulation system of Fiber Bragg Grating sensor is complex ,expensive,big size and so on .This paper presents a portable a demodulation system of fiber grating sensor based on DSP.The principle of wavelet-denoise is analyzed based on wavelet transform and Mallat algorithm,and digital signal processor TMS320LF2407A is used to decompose and reconstruct noise FBG reflecting spectrum to realize real-time wavelet-denoise.The design of hardware and software is given and Correlative simulation test is carried out,which proves the feasibility that wavelet-denoise is processed on DSP.
