REFLECTOR OF PHOTOELECTRIC AUTOCOLLIMATION ANGLE METER Russian patent published in 1996 - IPC

FIELD: monitoring and testing technique. SUBSTANCE: reflector is in the form of a trihedron, having two flat reflecting faces and one cylindrical face. A generatrix of the cylindrical face is parallel with one of the flat faces, another flat face is inclined relative to the first flat face by an angle (90^°-δ), and relative to the generatrix of the cylindrical surface-by and angle (90^°+δ).. A particular value of δ is determined according to constructive parameters of the angle meter, using the reflector. EFFECT: enhanced accuracy of angle measuring, high information content due to determination of twisting angle. 1 cl, 7 dwg, 6 tbl
