Scatterometric is a technical term used in the field of optics and material science to describe a measurement technique that involves measuring the scattering of light from a surface or material. There are several synonyms and related terms that can be used instead of scatterometric, including scatterometry, optical metrology, light scattering, and angle resolved scatterometry. These terms are often used interchangeably to describe the same measurement technique, and all involve the use of light scattering to extract information about the properties of a material or surface. Because of its widespread use in the field of optics and materials science, scatterometric measurements have important applications in areas such as semiconductor manufacturing, nanotechnology, and lithography.
