摘要
噪声免疫腔增强光外差分子光谱技术(NICE-OHMS)结合了频率调制光谱和腔增强吸收光谱两种技术,是目前探测灵敏度最高的激光吸收光谱技术。首先介绍NICE-OHMS技术的基本原理和实现过程,然后概括其发展现状,重点介绍各个课题组采用的激光源、腔的精细度等关键参数,及其对探测灵敏度的影响,最后提出限制NICE-OHMS技术探测灵敏度的主要因素及其解决方案。
Noise immune cavity enhanced optical heterodyne molecular spectroscopy（NICE-OHMS）can provide the highest detection sensitivity in the field of laser absorption spectroscopy by combining two techniques of frequency modulation spectroscopy and cavity enhanced absorption spectroscopy.The principle and implementation process of NICE-OHMS are introduced.Then,the historical development of NICE-OHMS is overviewed,which mainly focuses on the key parameters,such as the applied laser source and the cavity finesse used by each research group and their obtained detection sensitivity.Finally,the limitation factors of the detection sensitivity of NICE-OHMS are analyzed,and the related solutions are provided.
