Abstract:
We demonstrate a novel approach for the simulation of miniaturized non-resonant photoacoustic gas spectroscopy (PAS) sensors by applying a one-dimensional signal flow model. Using the described method, these non-resonant PAS sensors systems can be optimized with regard to their applicability to different target gases. The model is validated with lab measurements and reveals potentials and limitations with a view to optimization endeavours.
