提出了一种基于椭偏仪的磁盘上分子润滑膜的直接可视化方法。分子膜的可视化对于研究润滑膜的补充和保持特性是非常有用的。将样品表面的椭偏信息转换为暗-亮对比度图像，然后用CCD摄像机直接可视化。通过光学和数字图像处理技术的结合，增强了弱对比度，降低了噪声强度。因此，我们的方法可以提供1纳米量级的润滑膜的直接可视化。
An ellipsometry-based direct visualization method for molecularly thin lubricant films on magnetic disks is presented. Visualization of a molecularly thin film is useful for the investigation of replenishment and retention characteristics of thin lubricant films. Ellipsometric information of a sample surface is converted into a dark-bright contrast image and then is directly visualized with a CCD camera. By combining of optical and digital image processing techniques, weak contrasts are enhanced and noise intensity is reduced. Thus, our method can provide direct visualization of thin lubricant films on the order of 1 nm.
