Profilometry is a measurement technique used to analyze the surface profile of an object. It helps in determining the roughness, texture, and other surface characteristics by creating a detailed map of the surface features. This technique is widely used in various fields, including manufacturing, materials science, and quality control. There are different types of profilometers, such as contact and non-contact methods. Contact profilometers use a stylus that physically touches the surface, while non-contact profilometers utilize light or laser technology to capture surface details without direct contact. Both methods provide valuable data for improving product quality and performance.
