摘　　要：表面形貌的精确描述在许多领域诸如材料、生物医学、摩擦学和机器状态监测等领域变得越来越重要。开发了一种基于激光共焦显微镜和图像处理技术的研究磨损表面及表面参数的新方法。首先用B io-rad Rad iance 2000激光共焦显微镜方法获得精确的三维表面形貌,然后用计算机辅助图像分析技术自动计算出表面特征参数。应用示例表明本文所研究的方法是可靠的,能对工程表面的表面粗糙度特征进行精确描述。The accurate characterization of surface topography has become increasingly important in many fields, such as materials science, the biomedical industry, tribology, and machine condition monitoring. A new approach to gain surface parameters to characterize worn surfaces using confocal laser scanning microscopy and image processing technique was proposed. Bio-rad Radiance 2000 confocal laser scanning microscopy is firstly used to acquire appropriate 3D surface topography. Computerized image analysis techniques are then adopted to quantify surface parameters, An application example on engineering surfaces was presented to demonstrate that the developed method can be used to describe surface characteristics reliably and precisely.
