Frequency-Domain Detection for Frequency-Division Multiplexing QEPAS
To achieve multi-gas measurements of quartz-enhanced photoacoustic spectroscopy (QEPAS) sensors under a frequency-division multiplexing mode with a narrow modulation frequency interval, we report a frequency-domain detection method. A CH<sub>4</sub> absorption line at 1653.72 nm and a CO<sub>2</sub>...
