Profilometrija

Profilometrija is a technique used to measure the surface topography of an object. It involves scanning a surface with a probe or beam of light and recording the variations in height. This allows for the creation of a three-dimensional map of the surface, revealing its texture, roughness, and overall shape. Profilometry finds applications in various fields, including manufacturing, research, and quality control.

There are several types of profilometry. Contact profilometry utilizes a physical stylus that traces the surface. While accurate, it can potentially scratch or damage delicate surfaces. Non-contact profilometry employs optical methods, such as white light interferometry or confocal microscopy, which use light to measure surface height without physical contact. This makes it suitable for a wider range of materials.

The data obtained from profilometry can be analyzed to determine various surface parameters. These include average roughness (Ra), root mean square roughness (Rq), and peak-to-valley height (Rz). These measurements are crucial for understanding a material's performance, such as its wear resistance, friction characteristics, and optical properties. Profilometry is an essential tool for ensuring the quality and functionality of manufactured components and for scientific investigations into surface phenomena.
