Description

一种多组分气体光谱测量***
技术领域
本实用新型涉及一种光谱测量***，尤其是涉及一种测量空气中有害气体的多组份气体监测***。 
背景技术
在大气污染中气体的监测中，可根据不同气体的吸收光谱特征不同，分别采用多台仪器进行测量。但这种方法成本很高。也可采用开放式长光程法监测***，由于光谱仪分辨率的限制，一般只局限于紫外或红外一个较小波段内的光谱测量，所以测量气体的组分比较少，如在红外波段可同时监测CO、CO2、CH4，在紫外波段监测O3、SO2、NO2，但以上气体一般不能同时都进行监测。 
实用新型内容
本实用新型的目的是解决光谱分析方法不能同时监测多种气体成份和浓度，提供一种多组分气体光谱测量***。 
光源发出的光经光学***后反射进入接收端，携带气体信息分别经光谱接收装置接收后由计算机进行分析。该***通过一套光学***可以同时测量紫外和红外的光谱信息，可同时完成紫外、红外波段的多种气体吸收光谱测量。 
本实用新型提供的多组分气体光谱测量***，包括紫外光源、红外光源、传输光纤、光学准直及聚焦***及紫外、红外光谱接收装置。光源发出的光经准直后射出，经远方的角锥棱镜反射后进入接收端，携带气体信息分别经光谱接收装置接收后由计算机进行分析。 
本实用新型的优点和积极效果：该***通过一套光学准直及聚焦***可以同时测量紫外和红外的光谱信息，可同时完成紫外、红外波段的多种气体吸收光谱测量。 
附图说明
图1是本实用新型提供的多组分气体光谱测量***结构示意图。 
具体实施方式
如图1所示，该***包括紫外光源1、红外光源2、光学***、紫外光谱仪8、红外光谱仪9。其中光学准直及聚焦***包括：球面反射镜6及角锥棱镜7。此外该***还包括收发光纤束，该光纤束由发射光纤10、11和接收光纤12、13构成。检测时，由紫外光源1、红外光源2发出的光谱分别耦合进入发射光纤10、11，由另一公共端5射出，经光学***的球面反射镜6准直，通过一段开放的气体，到达远处的角锥棱镜7，然后被沿原方向反射，携带气体信息的反射光沿原方向返回，再次经光学***的球面反射镜6聚焦进入收发光纤公共端5，最后经接收光纤12、13出射后分别导入紫外光谱仪8、红外光谱仪9进行光谱检测。
