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(4) absorption line at 1653.72 nm and a CO(2) absorption line a...
