摘要：

A novel quartz-tuning-fork (QTF) chopper was developed for quartz-enhanced photoacoustic spectroscopy (QEPAS). Unlike the conventional wavelength-modulation-based QEPAS, the QTF chopper chops the continuous wave excitation light into a sequence of light pulses, which realizes the amplitude-modulation (AM)-based QEPAS. In order to reduce the chopping noise and to make the resonance frequency of the QTF chopper perfectly match that of the detection QTF, a careful design and optimization were implemented. The performance of the AM-based QEPAS sensor for detection was also evaluated in detail.
