title = "Everything at Once - Linearizing System Response and Enhancing Sensitivity in Photoacoustic Gas Sensors by Dedicated Demodulation and Filter Tuning Methods",
abstract = "We present a sophisticated method for improving the sensitivity of CO2-detecting non-resonant MEMS-based photoacoustic gas spectroscopy systems by more than 50 \% compared to state-of-the-art approaches. The method based on signal demodulation can also be used to linearize the measured system's response in order to reduce the calibration effort for future sensors. Tuning the filter transmission spectra accordingly is utilized to further increase the linearity of the system response and enhancing the sensitivity by more than 200 \%.",
