Abstract

An installation for measuring the angles of polyhedral prisms is considered, in which autocollimators with digital registration of the coordinates of the optical mark are applied. Algorithms for solving systems of equations for the determination of angles by the method of aggregate measurements with the help of two and three autocollimators are described. The errors in the measurements are calculated and compared with the results of experimental measurements of the angles of polyhedral prisms.
