摘要
综述了光学气体吸收池在可调谐半导体激光器吸收光谱技术(Tunable DiodeLaser Absorption Spectroscopy,TDLAS)领域中的应用和发展。通过介绍多种类型吸收池,包括White型、Herriott型、矩阵型以及它们的改进型等吸收池的结构和原理,对现有吸收池的优缺点进行了分析。根据TDLAS技术的发展需求,指出了光学吸收池小型化、易操作、高稳定性和同时测量多种气体的发展趋势。
The applications and development of optical gas cells in tunable diode laser absorption spectroscopy （TDLAS） are overviewed. The structures and principles of several types of absorption cells including the While, Herriott, matrix and other improved cells are presented. The advantages and disadvantages of the current cells are analyzed. According to the demand of TDLAS technology, the trend of optical absorption cells to be smaller, simpler and more stable while measuring multiple gases is pointed out.
