Novel approach for efficient resonance tracking in photoacoustic gas sensor systems based on a light-induced wall signal
Photoacoustic gas sensing is a method suited for the detection of radiation absorbing molecular species in the gas phase. Due to the backgroand-free detection, it has considerable benefits in the measurement of very low concentrations down to the parts-per-trillion range. Yet in resonant systems, th...
