Abstract:
1. A construction laser system comprising: a rotation laser having a laser unit and a continuously rotatable deflection means for emission of a rotating laser beam that defines a reference surface; a laser receiver having a laser beam detector extending at least over a one-dimensional region on the laser receiver, so that the laser receiver generates an output signal as a function of incidence of the laser beam on the laser beam detector; an evaluation unit for determining a laser receiver direction, in which the laser receiver lies in sight of the rotation laser; a memory that stores: a control unit for control, synchronized with rotation of the deflection means, of the laser unit in relation to the generation of the at least two different discrete states, such that, in the respective rotation angle ranges, the sequence of states relating to the laser beam, which corresponds to the respective rotation angle range, is respectively generated in the course of a series of rotational passes of the deflection means by successively occurring crossings of the respective rotation angle range, wherein the evaluation unit:
