摘要
基于谱线的相对强度法,开发了激光焊接光致等离子体电子温度和密度的测量系统,包括了分光与色散系统,信号采集与预处理系统,以及数据后处理与显示系统。试验结果表明,硬件设计和软件系统的开发与集成满足了激光焊接光致等离子体电子温度和密度的测量要求。
Based on the relative intensities of atomic lines, a measurement system including spectroscopy system, signal acquisition and pre -process system, and data post -process and display system, was developed for measurements of electron temperature and density of laser induced plasma. Experiments results show that hardware design and software development meet the requirements for measurement of electron temperature and density of laser induced plasma.
