Ways of improving autocollimation sensors for monitoring angular displacements are analyzed. The results of an analysis of control elements based on tetrahedral reflectors with flat and cone reflecting sides are presented. The technical characteristics of experimental models of control elements are presented. The features of tetrahedral reflector as the control elements for three-axis angular sensors are discussed.
