Abstract
The invention relates to a laser system (100) comprising a laser receiver (10) and a laser emitter (20) and to a method using this system (100). The laser receiver is designed for locating a laser beam (22) relative to the laser receiver (10) by its laser light photo sensor (1). The laser receiver (10) has an acceleration sensor (4) providing a signal indicating a movement of the laser receiver together with a movement direction and an acceleration of this movement and a circuitry (3) connected to said photo sensor (1) and to the acceleration sensor (4) designed to compute and correlate the signals of photo sensor (1) and acceleration sensor (4) and to weight the information derived from the acceleration sensor (4). Laser receiver and laser emitter of the laser system are both provided with communication means, so that by communicating the weighted information the laser plane can be adjusted and/or re-adjusted in response to a movement of the leaser receiver.
