ABSTRACT:
The process as claimed in the invention for alignment of machines, machine elements or the like, especially of pipes or hollow cylinders is carried out by means of the pertinent devices such that in one of two measurement phases with the light transmitting and receiving device (20) fixed, rotation of the reflector prism (60) takes place in at least 3 optionally selectable rotary positions together with the pertinent data acquisition, and in the other of the two measurement phases with the reflector prism (60) fixed, rotation of the light transmitting and receiving device (20) takes place in either 2 predefined rotary locations at a right angle to one another, or 3 or more optionally selectable rotary positions together with the pertinent data acquisition.
