为解决快脉冲等离子体光学诊断中所用的多幅分光延时干涉系统光路复杂、无法同时调出多幅背景条纹平行、平直的干涉图的困难,在原有设备的基础上,将实时全息方法应用于多组物参光的干涉显示,在实验现场恶劣的环境条件下成功地一次采得5幅条纹平直均匀的干涉图,取得了较好的结果,为场分布量的定量测量读数奠定了基础。结果表明,实时全息具有多方面的优越性,不失为其它光学、干涉方法难以奏效的复杂光学系统及多种极端物态显示研究中的有效手段。
In order to solve the difficulties of multi-spectral time-delay interferometry system used in the optical pulse diagnosis of fast pulse plasma, it is difficult to draw parallel and straight interferograms of a plurality of background fringes at the same time. On the basis of the original equipment, a real-time holographic method The interference applied to the multi-component ginseng shows that the five interference fringes with uniform and uniform fringe pattern are successfully obtained at a time in the harsh environment of the experimental site, and the good results are obtained. The quantitative measurement reading of the field distribution amount is laid The foundation. The results show that the real-time holography has many advantages and can be regarded as an effective method for complex optical systems and other extreme state display studies that are difficult to be performed by other optics and interference methods.
