Paper Abstract

An autocollimator designed for measuring the three angular coordinates of a rotating object was examined. The impact of the principal primary errors of an autocollimation angular-measurement system on the error in measuring the axis position and magnitude of a rotating object was analyzed. A computer model of an autocollimation system was built based on describing object rotations using quaternions method. The autocollimation measurements algorithms were compared based on the quaternion and matrix models using the autocollimator parameters deviations effect on the total measurement error. Results of experimental research of the two versions of tri-coordinate autocollimation systems were described: one of them used a matrix model and another one – a quaternionic theoretical model. Autocollimator reflectors in the form of two-sided, tetrahedral and pyramidal prisms were investigated and rotation measurement errors were calculated.
