用于燃烧场诊断的自发拉曼光谱检测仪器

The Spontaneous Raman Instrument Special for Combustion Diagnosis

燃烧场光谱学诊断方法由于具有高灵敏度、非介入式、高空间分辨率及实时响应的特点现已成为火焰在线检测的有效手段,由于火焰中物质存在方式及其所处环境的特殊性,对检测仪器提出较高的要求。详细介绍了用于瞬态燃烧场自发拉曼光谱(SRS)检测的光学系统组成及其搭建要点,并对瞬态光谱系统的同步调试进行介绍,分析了影响拉曼信号质量的仪器及操作方法等因素。

Due to high sensitivity,noninvasive,high spatial resolution and real-time response,the combustion diagnosis by spectroscopy has become an effective method to detect the flame.Since the substance in flame is under extreme condition,which ask for a high demand on the detecting instrument.In this article,the optical structure of the combustion diagnosis system and its key design points are detailed introduced.Also,we describe the way of synchronous debugging and analyze the main factors that affect the signal quality.
