A distance measuring arrangement for determining a distance from an object includes at least one light source for producing at least one first monochromatic and interference-capable light beam with a first wavelength and at least one second monochromatic and interference-capable light beam with a second wavelength, a multiplexer for coupling or combining the at least one first light beam and the at least one second light beam into a common measurement beam, an output coupling element for splitting the measurement beam into a reference beam and a signal beam, wherein the reference beam propagates along a reference path and wherein the signal beam propagates along a signal path, and a phase modulator that is arranged in the signal path and configured to modulate the phase of the signal beam periodically in time.

Distance measuring arrangement for determining a distance from an object

A device and method for geometrically measuring an object includes a carrier for the object, at least one reference object that can be fixed relative to the carrier, and a holder which can be moved in at least one direction (x,z) relative to the reference object and on which a reference body and a distance measuring device are arranged, which distance measuring device is designed for measurement of a distance between the object and the reference body. A first and a second reference sensor are arranged at a distance from each other on the holder or on the reference body while facing the reference object, said reference sensors being designed to measure a first and a second distance to the reference object.

Device and method for geometrically measuring an object

A device and method for geometrically measuring an object, with a base and a carrier device arranged thereon for the object, at least one reference object which can be fixed relative to the base, at least one distance measuring system, by means of which a distance between the reference object and the surface of the object facing the reference object can be determined, and an object holder having an upper side and a lower side, to which the object can be attached, wherein the object holder can be selectively arranged in a first orientation and a second orientation on the carrier device, wherein the distance measuring system and the object holder are movable relative to each other in order to scan the surface of the object, and the object holder has on the upper side thereof and on the lower side thereof respective reference structures.

A device for measuring at least one surface portion of an object has a holder on which a reference body and a distance measuring device are arranged. The distance measuring device is pivotally mounted on the holder relative to a first axis and relative to a second axis. The distance measuring device is operable to determine a distance from a first point located on the surface portion of the object and a second distance from a second point located on the reference body.

Method and device for highly-precise measurement of surfaces

A device and a method for measuring at least one surface section of an object that is mounted on a carrier includes at least one reference object that can be fixed relative to the carrier, and a holder that can be moved relative to the reference object in at least one first direction and on which a reference body and a distance measuring device are arranged. The reference body and the distance measuring device are mounted in a rotatable manner relative to each other. The distance measuring device is designed to determine a first distance to a first point of the surface section of the object and a second distance to a second point of the reference body wherein the second point corresponds to the first point.
