Claim Text:
1. A laser system comprising a laser receiver collaborating with a laser emitter, the laser receiver is designed to detect the laser light beam of a laser emitter with a laser light photo sensor having a zero position and providing an electrical output signal when illuminated by a laser beam, the laser receiver further comprise a circuitry designed to receive and to compute the electrical output signal of said laser light photo sensor and a communication signal transmitter for communicating with the laser emitter using communication signals; the laser emitter is designed to provide a laser light plane and comprise a control unit connected to a communication signal receiver in order to work and compute the incoming communication signals from the laser receiver, wherein the laser emitter is provided with means for restricting the extent of the laser plane by beam masking or by limiting a pendulum motion of the laser beam between pre-defined end points; the laser receiver having an acceleration sensor designed to provide an electrical output signal indicating a movement of the laser receiver,
