Paper Abstract

Basing on Fabry-Perot fiber optic strain gauge integrated with DSP and the accomplished hard system, principle of Fabry-Perot fiber optic strain gauge integrated with DSP was discussed. Data collecting and processing method of real outputting signal were deeply discussed. Discrete gap transform (DGT) is presented based on FFT and used to obtain the gap of Fabry-Perot fiber optic sensor.DGT completes the direct transformation of the signal from wavelength domain to cavity length domain. In addition, the experiments based on equal strength beam system were carried out. Experimental result shows that previous data processing method is effective. The result is primarily in accordance with that of real loading processing, and shows the method developed by this paper is feasible and effective.
