    Photoacoustic Detection of Methane in Large Concentrations with a Helmholtz Sensor: Simulation and Experimentation

    We report on the use of a photoacoustic Helmholtz sensor for the detection of large concentrations of methane. In this case, methane is in concentration where the photoacoustic signal is no more linear with co...
