增强吸收光谱技术的研究进展及展望
Development and prospects of enhanced absorption spectroscopy
摘要
Abstract
Optical path absorption spectroscopy is an important branch of absorption spectroscopy.In recent years,there has been a proliferation of optical path absorption spectroscopy techniques based on different light source technologies,absorption cavity technologies,and detection methods.As the demands on detec-tion sensitivity and absorption optical path length increased,optical path absorption spectroscopy techniques based on the principle of enhanced absorption emerged,including integrated cavity spectroscopy(ICOS),cavity-enhanced absorption spectroscopy(CEAS)and cavity ring-down spectroscopy(CRDS).Enhanced ab-sorption spectroscopy is advantageous for its high spectral resolution,high sensitivity,fast response time,and portability,but it presently lacks a unified concept and clear classification criteria.This paper compares the development history of absorption spectroscopy techniques and clarifies the concept of their multi-optical path.Based on whether resonant absorption occurs in the absorption cavity,the concept of absorption spec-troscopy techniques based on resonance is proposed,and the current research status of resonant absorption spectroscopy techniques is analyzed and summarized,and the applications of this technique in various fields are outlined.Finally,the future development of key technologies in resonance absorption spectroscopy is en-visioned.关键词
