英文摘要An ultra-compact acoustic detection module (ADM) was developed for trace gas detection by use of quartz-enhanced photoacoustic spectroscopy (QEPAS). Different from the conventional QEPAS ADM, a gas enclosure was employed to confine the photoacoustic waves and excite the acoustic azimuthal and radial modes. Finite element modelling (FEM) method was used to analyze the acoustic modes and pressure distribution. The geometrical parameters of the ADM were optimized to enhance the sensor performance. The developed QEPAS ADM was only similar to 0.05 mL and similar to 0.15 g, significantly reducing the QEPAS sensor volume and weight, and improving the QEPAS system gas flush time by orders of magnitude. As a proof of concept, H2O was detected by the ultracompact spectrophone employing a telecommunication diode laser. A detection limit of 2 ppm was achieved.
