Surface Profilometry is a technique used to measure the surface texture and topography of materials. It provides detailed information about surface features, such as roughness, waviness, and texture, which are important for various applications in engineering and manufacturing. This method can be performed using different tools, including contact profilometers and non-contact profilometers. Contact profilometers use a stylus that physically touches the surface, while non-contact methods, like optical profilometry, use light to capture surface details. Both techniques help in quality control and research by providing precise measurements of surface characteristics.
