With micro- and nano-structured optical fibers, parts-per-million to parts-per-trillion level gas detection has been demonstrated for a range of gases such as methane, acetylene, ethane, carbon monoxide, hydrogen, and oxygen. We review the recent development in optical fiber gas cells and gas detection systems based on direct absorption, photothermal, photoacoustic, and stimulated Raman spectroscopies.

微/纳米结构光纤在光谱气体传感中的最新进展

使用微米和纳米结构的光纤,已证明对百万种气体(百万分之一到百万分之几)的气体检测范围包括甲烷,乙炔,乙烷,一氧化碳,氢气和氧气。我们回顾了基于直接吸收,光热,光声和受激拉曼光谱学的光纤气室和气体检测系统的最新发展。
