Abstract

Based on optical fiber grating sensing technology, the signal processing system of smart clothes was designed. The clothes embedded in fiber Bragg gratings (FBGs) sensor can measure the body physiological parameters, such as temperature, and detect the healthy condition of wearer. The paper presented FBG wavelength detection and signal processing methods with wearable characteristics, designed optical scheme and demodulated circuit in terms of tunable F-P filer wavelength demodulation theory. The numerical arithmetic of processing wavelength data was researched and realized in ARM. By testing, the measuring scope of wavelength is from 1520.5 to 1562nm, and the resolution of wavelength can arrive at 2pm. By selecting appropriate center wavelength of sensing gratings and referenced gratings, the relative error of wavelength can less than 0.001%. The signal processing system can adjust the excursion of F-P cavity timely, and has characters of portability, wireless data transmission.
