    Abstract

    As one kind of photoacoustic spectroscopy technology, quartz-enhanced photoacoustic spectroscopy gas sensor has advantages of high sensitivity, high selectivity and rapid response. Tuning fork and micro resonance tubes is used instead of photoacoustic cell and microphone to realize quartz-enhanced photoacoustic spectroscopy detection. Micro resonance tubes is used for signal enhancement. Three types of coupling configuration mode between tuning fork and micro resonance tubes are analyzed and compared. The factors which affect the signal amplitude and signal to noise ratio are also analyzed. The progress in terms of parameters optimization is summarized. On basis of the analysis, the latest progress in spectraphone is also provided. In addition, a new type of terahertz quartz-enhanced spectraphone is introduced, which uses a custom made quartz tuning fork. With the development of mid infrared laser source,quartz-enhanced photoacoustic spectroscopy will not be confined by the limitation of beam quality , and will be used more widely.
