Frequency Division Multiplexing and Normalized Harmonic Method for WMS Detection System in Multi-gas Detection
A frequency division multiplexing (FDM) WMS system for multi-gas detection is reported in this paper. The distributed feedback lasers with different wavelengths adopt different modulation frequencies to achieve multi-components gas detection by the FDM technology. Combining optical path extension, n...
