Abstract

The report presents results of analysis and experimental research of the laser goniometer in the mode of operation – noncontact measurements of an object’s angular position. An important feature of this mode is an extremely large range of measurement with high accuracy. With the usual resolution of about 0,1 arcs the laser goniometer has in this mode of operation an essential advantage against photo-electric autocollimators with their rather small measuring range. Obtained results confirm that the laser dynamic goniometer using in the mode of non-contact measurement of an object’s angular position can be characterized by the range of angle measurements up to 15…20 deg and accuracy of constant angles on the level 0,05…0,1 arcs. The error of angles changing in time has additional components on the level of 0,2 arcs connected with influence of optical polygon face unflatness and difficulties of use the statistical averaging of measurement results.
