| Abstract: | A novel system for multiplexed optical fiber interferometric sensors is proposed applying the synthesis of optical coherence function with phase generated carriers. The ideal parameters of the laser diode frequency modulation for the phase generated carrier with the synthesis of the optical coherence function are discussed. A basic experimental setup including two interferometric sensors is constructed. The results show that the phase signal from the two sensors can successfully be demultiplexed by scanning the synthesized coherence peak. |
