The article is based on some research which is considering the three-axis angle measuring autocollimator with one channel capable of measuring three angular coordinates simultaneously. In order to measure angular displacements around the three main coordinate axes (OX, ОY, and ОZ), special control elements are used. The use of a special control element generally improves the characteristics of the device, but it creates a problem of autocollimation mark overlapping. This issue creates a zone of inoperability of the device and makes measurement and control impossible. The ways of solving this problem are not considered in this paper. The prototype of an optoelectronic joined-channel autocollimator with a tetrahedral control element is developed. The developed prototype passed functional testing, calibration was conducted with using a flat mirror. The paper also shows the results of the research device accuracy in the measurement of different angles.
