Abstract

The report describes the laser goniometer intended for calibration of a circular optical encoders. This is one of the most perspective systems based on the rotating ring laser. This system provides the calibration of every line of optical encoder even if number of lines achieves one hundred thousands or more. The system operates in fully automate mode and calibration procedure takes very small time. The accuracy of calibration is on the level of 0,1 arcs. The rotation rate range is up to 5...10 revolutions per second. The important feature of the system is ability to measure dynamic error of optical encoder. The schematic of the system, analysis of errors, examples of implementation are considered in the report. The important part of the report is devoted to metrological support of calibration of an optical encoders. The angle standard based on the ring laser and the holographic optical encoder with systematic error on the level of 0,01 arcs is described also in the report.
