The Compensation for Abbe Error in the Leveling Rod Tests Systems Useing Laser Interferometer

The new test standard for levelins rod requires using laser interferometer. The Abbe error is the main resource of errors in the test system. This paper established a new method to compensate the error. The example explain that the method not only has high precision,but also simplifies the mechnical design. The compensate theroy also can be used in other laser interferometer distance measurement system.
