中文摘要	为了给从事红外混合气体检测领域的研究人员提供一定的借鉴与参考,针对红外混合气体检测系统中的光学复用结构以及检测方法进行了详细评述。目前,以量子级联激光器(QCL)、带间级联激光器(ICL)为代表的相干光源已逐渐取代热辐射红外光源、红外发光二极管(LED)等传统非相干光源,成为红外混合气体检测中的主流光源。相应地,具有超高探测度和极短响应时间的红外光探测器也逐渐超越以往的红外热探测器,占据红外探测器领域的主导地位。基于"复用思想"的光学复用结构则是红外混合气体检测系统的核心,主要包括单光源复用检测结构和多光源复用检测结构。其中,单光源复用检测结构以其体积小、集成度高等优点成为构建便携式混合气体检测系统的重要选择;而多光源复用检测结构是时分复用、频分复用、波分复用等思想的具体化,并凭借其较宽的光谱覆盖范围、较高的光谱分辨率等优势成为当前混合气体检测系统中的主导结构。应用于红外混合气体检测的检测方法主要有非分光红外(NDIR)光谱技术、波长/频率调制光谱技术、腔增强光谱技术以及光声光谱技术等。研究人员可通过对红外混合气体检测系统各组成部分充分了解后,设计出实用的红外混合气体检测系统,对工农业生产、环境监测、生命科学等诸多领域都具有重要意义。; In order to provide the experiences and references to the researchers who are working on infrared(IR)mixed gas detection field.The proposed manuscript reviews two sections of the aforementioned field,including optical multiplexing structure and detection method.At present,the coherent light sources whose representative are quantum cascade laser(QCL)and interband cascade laser(ICL)become the mainstream light source in IR mixed gas detection,which replace the traditional non-coherent light source,such as IR radiation source and IR light emitting diode.In addition,the photon detector which has a super high detectivity and very short response time is gradually beyond thermal infrared detector,dominant in the field of infrared detector.The optical multiplexing structure is the key factor of IR mixed gas detection system,which consists of single light source multiplexing detection structure and multi light source multiplexing detection structure.Particularly,single light source multiplexing detection structure is advantages of small volume and high integration,which make it a plausible candidate for the portable mixed gas detection system;Meanwhile,multi light source multiplexing detection structure is embodiment of time division multiplex,frequency division multiplexing and wavelength division multiplexing,and become the leading structure of the mixed gas detection system because of its wider spectral range,higher spectral resolution,etc.The detection method applied to IR mixed gas detection includes non-dispersive infrared(NDIR)spectroscopy,wavelength and frequency-modulation spectroscopy,cavity-enhanced spectroscopy and photoacoustic spectroscopy,etc.The IR mixed gas detection system designed by researchers after recognizing the whole sections of the proposed system,which play a significant role in industrial and agricultural production,environmental monitoring,and life science,etc.
