The invention relates to a laser receiver (10), comprising a laser light photo sensor (1) having a photo sensitive element (2) with a zero position and providing an electrical output when illuminated by a reference laser beam (22), and a circuitry (3) connected to said photo sensor (2). The laser receiver (10) has an acceleration sensor (4) connected to the circuitry (3) and providing a signal indicating a movement direction of the laser receiver (10). The circuitry (3) of the laser receiver (10) is designed to derive a relative movement of the laser receiver with respect to the laser beam (22) from computing and correlating the signals of the acceleration senor (4) and the laser light photo sensor (1). The invention also relates to a laser system comprising a laser emitter and such a laser receiver (10) and the use of such a system for guiding and controlling a construction machine.
