EXPERIMENTAL STUDY OF THREE-COORDINATE AUTOCOLLIMATION SYSTEM
Annotation
Two algorithms of autocollimation measurements of spatial rotation of an object based on matrix and quaternionic theoretical models are studied experimentally. The experiments were performed with a model of three-coordinate autocollimation system using glass tetrahedral reflector with the dihedral angles between the reflecting faces slightly deviating from right angle. The advantage of the quaternionic algorithm is demonstrated using reduction of the measurement error as a criterion.
