Surveying device comprising a base defining a base axis (A), a support structure arranged to be rotatable around the base axis (A) and defining a rotation axis (B), a light emitting unit for emitting measuring signal and a light receiving unit comprising a detector for detecting reflected measuring signal. A rotation unit is mounted on the support structure for providing emission and reception of measuring light in defined directions, wherein the rotation unit comprises a rotation body which is mounted rotatable around the rotation axis (B) and the rotation body comprises a scanning mirror which is arranged tilted relative to the rotation axis (B). The device comprises at least one projector fixedly arranged with the support structure, defining a particular optical axis and configured to direct a light pattern at a scene, wherein position and shape of the pattern are controllable by the controlling and processing unit.

A light receiver designed to determine a position or orientation relative to a reference light wherein the light receiver comprises an elongated rod-shaped light receptor with two ends, a light coupler, a light guide, and light detection means at both ends and a signal processor to process the electric signals of the detection means and to determine the relative position and/or orientation by a comparative evaluation of the electric signals. The light guide serves as a light propagation path of defined length for light coupled into the light guide by the light coupler and the signal processor determines the position and/or orientation based on light propagation speed of the reference light propagating in the light guide.

A method, device and system for automatically deriving stationing zones for an electronic measuring or marking device in a worksite environment. The method includes querying a database (DB) for a construction plan information for the worksite environment and acquiring a worksite-task-information of a worksite-task to be executed. The worksite-task-information includes spatial points in the construction plan which have to be measured and/or marked to accomplish the worksite-task. It also comprises an acquiring of at least coarse 3D-data of the actual real world worksite environment, and a merging of the at least coarse 3D-data and the construction plan information to form an actual state model of the worksite environment. An automatic calculating of at least one stationing zone within the actual state model is established, the stationing zone including at least one stationing location from which the measuring or marking of the spatial points are accessible by the device without obstructions.

A construction laser system includes a rotating laser with self-leveling and a laser receiver. The system performs a self-leveling recalibration process by which-the self-leveling is checked automatically for quality and the related calibration data is updated automatically. A sequence of N calibration measurements is defined, where N is greater than or equal to three. The calibration measurements are obtained by the rotating laser and the laser receiver with a respective azimuthal alignment of the stand while the position of the laser receiver remains unchanged. As part of each calibration measurement, one output signal dependent on the laser beam impingement position is detected. The respective output signals or specified impingement positions are evaluated in pairs correlated with the respective I-th azimuthal alignments. The quality of the beam leveling functionality is thereby checked. If the requirements are not met, the previously stored calibration data can then be updated automatically.

Disclosed is a method for removably connecting two groups of individual, parallel fibers that are delimited by end faces that are perpendicular to the fiber axis. The two groups of fibers are moved towards each other in an axial direction until each of the fibers abuts against the end face of the assigned fiber from the other group. The fibers of the two groups are aligned in pairs relative to each other before being moved into contact with each other, and any differences in fiber lengths is compensated for by elastically deforming the fiber along the fiber main axis. This method eliminates the disadvantages associated with bending the fibers because length variations are essentially compensated for by axially compressing the fibers.
