摘要
光声光谱技术用于探测痕量气体的浓度,小型化集成的光声光谱气体传感器利于实现便携式在线检测。光声探测作为光声光谱的关键技术决定了系统的灵敏度和体积,小型化的光声探测系统的核心是微型吸收单元和声光谐振器。总结了近年来光声光谱气体传感器在小型化与集成方面的进展,分析并比较三种光源、微型吸收单元以及小型化声光谐振器的研制进展以及各自利弊。介绍了北京航天控制仪器研究所近年的研究成果,采用共振管增强的石英音叉作为紧凑型封装的声光测量器件,通过铥钬共掺的光纤放大器实现波长为2 mm,功率为200 mW 的激光输出,提高了测量精度,实现对氨气和二氧化碳的同时测量。
Abstract
Photo-acoustic spectroscopy can be used to detect trace concentration gas. The total size can be made small, making it possible to realize portable in situ measurement. The critical technology of photo-acoustic detection is the miniaturization of absorption cell and microphone, which determines the sensitivity and volume of the system. Recent progress of photo-acoustic spectroscopy detection technology in miniaturization and integration is summarized. Three kinds of light sources, absorption cells and photo-acoustic resonators are analyzed and compared, respectively. Meanwhile, the latest progress of Beijing Institute of Aerospace Control Devices is also provided. The quartz tuning fork enhanced photo-acoustic spectroscopy technique is taken to realize miniaturization of absorption cell and photo-acoustic resonator. A compact packaged quartz tuning fork coupling with fiber is demonstrated. A Tm/Ho doped fiber amplifier is used to realize the 2 mm wavelength output with the power of 200 mW, and ammonia and carbon dioxide can be measured simultaneously.
