摘要
本文报道一种激光双波长实时显微全息干涉系统。该系统的光路设计很好地解决了激光双实时测量中的问题。利用该系统测量了甲醇 -乙醇 - CO2 等三元物系气液界面处液相侧的浓度场 ,得到了清晰的两个实时全息干涉条纹图 ,清楚地观察到了气液两相界面存在的湍动现象 ,从而验证了该系统的可靠性。
The composition and optical characte ri stics of a self-made,real-time and microscopic dual wavelength holographic in terferometer for visualizing the concentration profiles on gas-liquid interface were reported in this paper.The principle and methods of measurement were also presented in detail.Using this interferometer,the distinct real-time interferen ce fringes indicating the concentration profiles of the gas-liquid interface fo r the three-component system of methanol-ethanol-CO 2 were obtained.The i nterfacial turbulence was also clearly observed.
