摘要

Development of the measurement standard of a plane angle for reproduction of the size of plane angle unit in dynamic mode is described in the report. The development is based on the dynamic goniometer with the ring laser (RL) as angle sensor of super high resolution. The important feature of development is integration of angle sensors operating with totally different physical principles. In this purpose the holographic incremental optical encoder (OE) with 324 000 lines is included in the measurement system. The data processing in the system is carried out with the use of cross-calibration technique provided the determination of the systematic error of the RL as well as the systematic error of the OE. Experimental research showed that the random and residual systematic errors of the angle unit reproduction are on the level of 0,01 arc-sec.
