摘要
Using the principle of dual-channel cross correlation and the method of repeated sampling, a signal processing system to realize optical fiber ion concentration measurement is developed. A demodulation software is designed, which is effective for weak signal detection. The resolving power of this demodulation approach and its capability of improving signal-to-noise ratio (SNR) are discussed.
