| Abstract: | The program that the use of laser interferometer as a standard to replace the glass-standard is proposed. By adjusting the mirror on the platform of the length measuring system, the optical axis of laser interferometer coincides with the axis of the length measuring system. In this system, Abbe error can be eliminated. Simultaneously, the laser length measuring system errors was analysed, and the comparing experiment with gauge block was carried out The result demonstrated that this length measuring system can expanse testing and calibration range and improve the measurement accuracy. |
