The work concerns to the computerized techniques of quality estimation of automated top precision angle-code converters. Study of instrumental errors of a rotor position sensor (RPS) with use of goniometric rotary bench (GRB) was made, the plane angle accuracy being got from an optical interferential flat-mirror-zero-point module of original design and a photoelectric angle encoder ofRON-905 type manufactured by the <

The report is dedicated to research of systematic errors ofangle measurement by a dynamic laser goniometer (DLG) on the basis of a ring laser (RL), intended for certification of optical angle encoders (OE), and development of methods of separation the errors of different types and their algorithimc compensation The OE was of the absolute photoclcctric angle encoder type with an informational capacity of 14 bits. Cinematic connection with a rotary platform was made through mechanical connection unit (CU). The measurement and separation of a systematic error to components was carried out with applying of a method of crosscalibration at mutual turns OE in relation to DLG base and CU in relation to OE rotor. Then the Fourier analysis of observed data was made. The research of dynamic errors of angle measurements was made with use of dependence of measured angle between reference direction assigned by the interference null-indicator (NI) with a 8-faced optical polygon (OP), and direction defined by means of the OE, on. an.guiar rate of rotation.. The obtained results aiow to make algorithmic compensation of a systematic error and in the total considerably to reduce a total err . orof measurements.
