利用光学干涉法测量液体薄膜特性

Liquid thin films measurement based on optical interference

将光学干涉的原理与色度学方法相结合,通过计算机编程实现由颜色的色调值到光程差的转换,实现白光干涉图的计算机模拟,通过查表比色法还原薄膜厚度信息.测试了该方法用于理想薄膜和实际液体薄膜的厚度分布信息,效果良好.该实验可在实验室内完成,也可居家完成,可用于光电信息相关专业实验项目和课程内容的扩展.

The principle of optical interference was combined with colorimetric method to realize the conversion from the hue value of color to the optical path difference by computer programming and simulation of white light interferogram.By this method,the film thickness information of idea thin film and actual liquid film were restored.The experiment could be completed in the laboratory or at home and could be used to expand the experimental projects and course contents of photoelectric information related majors.
