Abstract:
    An invention of laser plane coordinate standard device contains three laser interferometry optical paths which measures the horizontal axial coordinate, it characterized in that a set of laser interferometry optical path which measures vertical axial coordinate is added, the interferometry optical path includes a vertical axis, object operating platform is located on the vertical axis and moves along the vertical axis drive by motor, pyramid reflector and survey target are mounted on the operating platform, a rotating prism which deflects the light path from horizontal axial to vertical axial is set on lower of operating platform. The device builds laser plane standard coordinate plane with two sets of mutually perpendicular laser interferometry optical paths, the structure is simple, accuracy of Abbe error compensation is high, measurement precision is high, direct calibration and error evaluation which is based on the coordinate points of large scale portable three-coordinate measuring machine are realized for the first time.
