Laser Interferometer Inspection of Granite Platform Flatness: Easy-to-Understand Principles I. Core PrincipleUtilizing the extremely high stability of laser wavelength, it precisely calculates the deviation of height undulations at every point on the platform through changes in interference fringes caused by optical path differences, and three-dimensionally fits the true flatness.The laser wavelength itself serves as a…
