Publication number: 20230408653Abstract: A measurement apparatus includes a light source, an interference optical system, a photodetector, a processing circuit, and a storage apparatus. The interference optical system splits light emitted from the light source into reference light and output light and generates interfering light between reflected light resulting from reflection of the output light on an object and the reference light.
