  • Abstract
    A method of improving the resolution and reliability of a laser interferometer which is used for measuring displacement is proposed. By giving code numbers to the divided segments of the interference fringe interval, the theoretical resolution is improved up to 1/170 of the light wave length. As the error caused by environmental noise is not integrated, the reliability is improved.
