  • How to measure light using a moving beam splitter

    How to measure light using a moving beam splitter

    The Michelson interferometer is an optical device that splits a beam of light into two paths, reflects them back, and recombines them to create an interference pattern. This creates two separate paths, which later overlap and interfere. This interference holds information about the light's wavelengths. The detector then turns this into usable data. The material you pick for the. What is a Michelson Interferometer? A Michelson Interferometer is an optical instrument used to measure very small distances, changes in refractive index, or wavelengths of light.
