基于AWG的多通道光纤光栅传感解调系统
Multi-channel FBG sensor demodulation system based on arrayed waveguide grating(AWG)
摘要
Abstract
A multi-channel fiber Bragg grating (FBG) sensor demodulation system based on arrayed waveguide grating (AWG) is designed, which includes light sources, isolator, coupler, optical loop device, FBG, AWG, photo-electric detector, the amplifying circuit, low pass filter circuit and the ARM control circuit. The temperature of FBG can be demodulated accurately with the technology of light intensity demodulation. The experimental re-sults show that the measured demodulation error of the demodulation system is not more than ±0.1℃, the de-modulation range of FBG center wavelength is 1 545.30-1 560.50 nm. This multi-channel FBG sensor demodula-tion system can calculate 32 FBG temperature sensors in 4-channel simultaneously.关键词
