"Acoustic Detection Module Design of a Quartz-Enhanced Photoacoustic Sensor." <i>Sensors,</i> 19, no. 5 (2019) MDPI: https://doi.org/10.3390/s19051093.https://hdl.handle.net/1911/107416This review aims to discuss the latest advancements of an acoustic detection module (ADM) based on quartz-enhanced photoacoustic spectroscopy (QEPAS). Starting from guidelines for the design of an ADM, the ADM design philosophy is described. This is followed by a review of the earliest standard quartz tuning fork (QTF)-based ADM for laboratory applications. Subsequently, the design of industrial fiber-coupled and free-space ADMs based on a standard QTF for near-infrared and mid-infrared laser sources respectively are described. Furthermore, an overview of the latest development of a QEPAS ADM employing a custom QTF is reported. Numerous application examples of four QEPAS ADMs are described in order to demonstrate their reliability and robustness.engThis is an open access article distributed under the Creative Commons Attribution License which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly citedJournal articleacoustic detection modulequartz tuning forkquartz-enhanced photoacoustic spectroscopysensors-19-01093-v2https://doi.org/10.3390/s19051093
