用干涉反射显微镜测量微流体实验中薄液膜轮廓的一种简单方法

A simple method of measuring profiles of thin liquid films for microfluidics experiments by means of interference reflection microscopy

V. Berejnov, D. Li

摘要:

本文提出了一种简单的方法来观察液体薄膜界面反射光的干涉图样。采用荧光显微镜与落射照明,我们收集了二维图案的干涉条纹包含信息的液体膜形貌在微观尺度上。为了证明所提出的可视化方法的实用性,我们开发了一个框架,通过分析反射的干涉图数值重建的液体膜的轮廓。可视化和重建方法应是有用的各种微流体应用涉及液滴和气泡的流动,其中的界面液膜的形貌的知识是至关重要的。

英文摘要:

A simple method was developed to observe the interference patterns of the light reflected by the interfaces of thin liquid films. Employing a fluorescent microscope with epi-illumination, we collected the 2D patterns of interference fringes containing information of the liquid film topography at microscale. To demonstrate the utility of the proposed visualization method we developed a framework for reconstructing the profiles of liquid films by analysing the reflected interferograms numerically. Both the visualization and reconstruction methods should be useful for variety of microfluidic applications involving the flows with droplets and bubbles in which the knowledge of the topography of the interfacial liquid film is critical.
