Abstract: The invention relates to a positioning apparatus, comprising a rotatable spindle, a sliding member, wherein a spindle counter segment of the sliding member is displaced along the spindle when the spindle rotates, a first guide for the sliding member, which interacts with a first guide counter segment of the sliding member and, in the process, leaves the sliding member with a linear mobility along the first guide axis and a pivotability about the first guide axis, and a second guide for the sliding member, which interacts with a second guide counter segment of the sliding member and, in the process, restricts the pivotability of the sliding member about the first guide axis.

Abstract: A method and device for displaying desired positions in a live image of a construction site. The method mat include recording at least one position-referenced image of the construction site; linking at least one desired position to the position-referenced image; storing the position-referenced image together with desired position linkage in an electronic memory; recording a live image of the construction site, in particular in the form of a video, wherein the live image and the position-referenced image at least partially represent an identical detail of the construction site; retrieving the stored position-referenced image from the memory; fitting the position-referenced image with the live image, so that the desired position linked to the position-referenced image can be overlaid in a position-faithful manner on the live image; and position-faithful display of the desired position as a graphic marking in the live image.

Abstract: An optical measuring device having a base for placing the measuring device and a targeting unit that is rotatable with respect to the base and defines a target axis for targeting a target object that is to be measured. The targeting unit has a first beam path for emitting optical measurement radiation in the direction of the target object that is to be measured. The targeting unit furthermore has a diffractive optical element (DOE), which is arranged or arrangeable in the beam path such that the optical measurement radiation is homogenized.

Abstract: The invention relates to a geodetic instrument, in particular a geodetic telescope, for example for a theodolite, or geodetic overview, photogrammetry or axial camera, comprising an imaging optical system which defines an optical axis and comprises an observation beam path for imaging a target object by an eyepiece and/or on a camera sensor, for registering and/or providing an image of the sighted target object. According to the invention, the imaging optical system comprises at least two diffractive optical elements in the observation beam path.
