摘要
增强石英音叉光声光谱技术作为光声光谱探测技术的一种,具有高灵敏度、高选择性、响应速度快的优势。增强石英音叉光声光谱技术采用可调谐石英音叉代替光声吸收单元和麦克风来实现光声信号探测,微共振管用来增强信号。分析并比较了三种音叉与微共振管耦合方式的增强石英音叉光声探测器,分析了影响系统信号强度与信噪比的因素,并总结了在参数优化方面的进展。在此分析基础上,介绍研制的小型化光声探测器装置和一种新型的太赫兹增强石英音叉光声探测器,并对其采用的定制音叉参数进行分析。随着新型中红外激光光源的应用,石英音叉光声探测装置会逐渐摆脱光束质量对其的限制,得到更广泛应用。
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.
