The invention relates to a laser system comprising a laser receiver collaborating with a laser emitter. The laser emitter is designed to provide a laser light plane and includes a control unit connected to a communication signal receiver in order to process and compute incoming communication signals from the laser receiver. The laser receiver comprising a communication signal transmitter for communicating with the laser emitter, a linear laser light photo sensor and an acceleration sensor both connected to a circuitry, which is designed to derive a movement of the laser receiver with respect to the detected laser beam of the laser emitter from computing and correlating the signals of the acceleration senor and the laser light photo sensor. The control unit includes an adjustment unit and adjustment is carried out by the adjustment unit in dependence of the processed and computed incoming communication signals of the laser receiver.

Laser receiver

The invention relates to a laser system () comprising a laser receiver () and a laser emitter () and to a method using this system (). The laser receiver is designed for locating a laser beam () relative to the laser receiver () by its laser light photo sensor (). The laser receiver () has an acceleration sensor () providing a signal indicating a movement of the laser receiver together with a movement direction and an acceleration of this movement and a circuitry () connected to said photo sensor () and to the acceleration sensor () designed to compute and correlate the signals of photo sensor () and acceleration sensor () and to weight the information derived from the acceleration sensor (). 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.

Construction laser system comprising a rotation laser and a laser receiver, and method

A device projecting a reference line, wherein at least one part of the reference path may be detected upon passing through by the human eye and/or detectors as a reference line. In conjunction with passing through the reference path, a distance measurement occurs to at least one point on the reference path by transmitting a measurement beam that is parallel or coaxial to the reference beam or using the reference beam as a measurement beam. After receipt of portions of the reflected measurement beam, a signal is derived from said portions and a distance from at least one point is determined from the signal, wherein the guidance along the reference path is repeated at least once more and, upon each instance of passing through the reference path, a distance or distance-related variable is determined for each point.

Distance-measuring method for a device projecting a reference line, and such a device

The invention relates to a device () projecting a reference line, having an electro-optical distance measurement unit that guides an optical reference beam (RS) along a defined reference path (RP), wherein at least one part of the reference path (RP) may be detected upon passing through by the human eye and/or detectors as a reference line. In conjunction with passing through the reference path (RP), a distance measurement occurs to at least one point (P) on the reference path (RP), particularly to a plurality of points (P), by transmitting a measurement beam that is parallel or coaxial to the reference beam (RS) or using the reference beam (RS) as a measurement beam. After receipt of portions of the reflected measurement beam, a signal is derived from said portions and a distance (D) from at least one point (P) is determined from the signal, wherein the guidance along the reference path (RP) is repeated at least once more and, upon each instance of passing through the reference path (RP), a distance (D) or distance-related variable is determined for each point (P).

A target plate (Z) according to the invention for positioning components, in particular pipes (R, R), has a holographic optical element as a holographic diffusor. By means of the diffusor, radiation striking the target plate (Z) in the form of a reference beam (RS) can be guided very accurately and virtually without loss into a defined solid angle region (d&#x3a9;). Furthermore, the diffusor may have stochastically distributed structures and thus illuminate the solid angle region (d&#x3a9;) homogeneously. By means of the target plate (Z), the visibility of the incident reference beam (RS) is increased, and the reference beam (RS) can also be detected independently of position.
