DIAGNOSTICS OF THE ARC PLASMA BY MONOWAVELENGTH PULSED LASER HOLOGRAPHIC INTERFEROMETRY

摘要:

本文阐述了单波长脉冲激光全息干涉法诊断电弧等离子体的原理及实验装置,提出了全息干涉图的解调方法,对自由燃烧氩弧进行了诊断,对诊断结果进行了误差分析和验证。结果表明,提供的诊断术和解调法是正确可靠的、行之有效的。本方法具有很大的应用潜力,特别有利于电弧等离子体动态过程和非常压电弧的研究。

Abstract:

This paper describes the general principle and experimental equipment of diagnosing are plasma by monowavelength pulsed laser holographic interferometry,The solution of the holographic interference patterns had been put forward and the free burning argon are diagnosed.The errors of diagnoses were discussed and the results verified.It is shown that the said technique and solution are effective and reliable.Wide application of this method is expected as it is particularly advantageous to the study of the are under non-normal pressure and the dynamic process of are plasma.
