Surface topography refers to the study and characterization of the physical features and characteristics of a surface, including roughness, texture, waviness, and form. This area of research is important in various fields such as engineering, manufacturing, geology, and material science, as it can affect the performance, functionality, and durability of materials and components. Surface topography analysis involves measuring and quantifying the surface features using techniques such as profilometry, interferometry, and microscopy. Researchers in this field aim to understand the mechanisms behind surface properties, develop methods for improving surface quality, and optimize processes for specific applications.
