Abstract
A construction laser system includes a rotation laser and a laser receiver. To determine a direction in which the laser receiver lies in sight of the rotation laser, a digital code respectively assigned uniquely to the respective rotation angle ranges includes a state value sequence based on a defined sequence of states relating to the laser beam. In the respective rotation angle ranges, the corresponding sequence of states is respectively generated by successively occurring crossings of the respective rotation angle range. On the receiver side, an output signal is generated as a function of incidence of the laser beam. With the aid of an output signal sequence of successively generated output signals, which is acquired by the evaluation unit, the state value sequence corresponding to the acquired output signal sequence is identified, permitting final determination of the corresponding rotation angle range in which the laser receiver lies.
