The PolySense team has just published a new article on Photoacoustics Journal Elsevier (IF 9.94) reporting on a photoacoustic spectroscopy (PAS) based gas senign approach exploting acoustic resonator to enhance acoustic wave and optical resonator to enhance optical wave. As demonstrator, we realized a sensor for acetylene (C2H2) detection achieved a noise equivalent absorption of 5.7 × 10− 13 cm− 1 and a dynamic range of eight orders. Compared to the state-of-the-art PAS gas sensors, the developed sensor achieves a record sensitivity and dynamic range.
