Abstract

A novel trihedral reflector (also known as hollow cube-corner reflector) with two cylindrical surfaces is proposed. This reflector has bottom side represented by two cylindrical surfaces, which axes constitute a 45° angle. Novel reflector solves the problem of an objects pitch measurement using singular cylindrical cube-corner reflector. Main benefit is that an image of this reflector consists of three lines, allowing to differ more consistently and to measure all three angles of object rotation.
