Abstract
A method for investigating the error of a laser dynamic goniometer by cross-calibration using a new calculation algorithm is proposed. The algorithm is based on the method of serial angle shifts of a polygon relative to ring laser of the goniometer. The results of using this algorithm for estimating the error of a laser dynamic goniometer are presented. The dominant source of error of this goniometer is determined ‒ the irregularity of the angular scale of the ring laser, which is caused by the slope of the scale to the axis of rotation of the goniometer spindle. Corrective corrections were calculated and introduced into the calculation algorithm, which allowed reducing the systematic error of the goniometer to 0.03″.
