Abstract

The wavelength division multiplex FBG sensor system was researched.The sensor array was designed, and this system was used in ocean water temperature detection.This experiment was achived in South China Sea with 300 meters long Bragg grating array and got original signal wavelength.The wavelength data was processed and transformed into temperature.By curve fitting,the seawater profile temperature can be obtained.Simultaneously,contrastive test was completed with CTD,which was recommended by experts. By processing the data with MATLAB,the resolution attained 0.1°C, and the precision attained 0.2°C,the temperature changed trends was the same with CTD,and small deviation was exsited.
