  • 摘要:

    光程吸收光谱技术是吸收光谱技术发展中的一个重要分支,近年来基于不同光源技术、吸收腔技术、探测方式的光程吸收光谱技术大量涌现。随着对探测灵敏度和吸收光程长度需求的提高,出现了基于增强吸收原理的光程吸收光谱技术,包括:积分腔光谱(ICOS)、腔增强吸收光谱(CEAS)和腔衰荡光谱(CRDS)。增强吸收光谱技术具有高光谱分辨率、高灵敏度、快速响应、便携等优势,但至今缺乏统一的概念和明确的分类依据。本文梳理了吸收光谱技术的发展历程,明确了多光程吸收光谱技术的概念。依据吸收腔内是否发生谐振吸收,提出了基于谐振原理的吸收光谱技术这一概念,分析总结了谐振吸收光谱技术的研究现状,并对这些技术在各领域的应用进行概述。最后,对谐振吸收光谱技术中关键技术的未来发展进行了展望。
