In this paper we propose an algorithm for autocollimators with cylindrical surfaced reflectors. We discuss it’s flow and how it can be achieved. Optimal flow can contain the following steps in the order, they should be performed: noise filtering, line width reduction, line separation, clustering, determination of an angle for each line.
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.
