  • Patent number: 8625106
    Abstract: In a method for optically scanning and measuring an object by a laser scanner by a procedure in which a emission light beam modulated with a target frequency is emitted by means of a light emitter, a reception light beam reflected or otherwise scattered in some way from an object in the surroundings of the laser scanner is received, with a measuring clock, as a multiplicity of samples by means of a light receiver and in each case at least the distance from the object is determined from the phase angles of the multiplicity of samples for a plurality of measuring points by means of a control and evaluation device, for determining the distances, a phase shift caused by a distance difference of temporal adjacent samples is corrected in order to correct the distances.

  • Publication number: 20120287265
    Abstract: In a device for optically scanning and measuring an environment, where the device is a laser scanner having a light emitter which, by a rotary mirror, emits an emission light beam, with a light receiver which receives a reception light beam, which, after passing the rotary mirror and a receiver lens which has an optical axis, is reflected from an object in the environment of the laser scanner. The laser scanner also includes a color camera which takes colored pictures of the environment of the laser scanner, and a control and evaluation unit which, for a multitude of measuring points, determines the distance to the object and links it with the colored pictures, the color camera being arranged on the optical axis of the receiver lens.

  • Patent number: 8064046
    Abstract: A method for determining a distance from an object may include emitting an emission light beam from a light emitter, receiving a reception light beam at a light receiver, and determining the distance on the basis of a propagation time of the emission and reception light beams. The reception light beam may arise as a result of reflection of the emission light beam at the object. The emission light beam may be amplitude-modulated with a rectangular-waveform modulation signal. The modulation signal may have a multiplicity of rectangular pulses which occur in a multiplicity of groups. The groups may occur at varying temporal intervals with respect to one another and have changing numbers of rectangular pulses.

  • Patent number: 7869005
    Abstract: A device for determining a distance from an object may include a light emitter for emitting an emission light beam, a light receiver for receiving a reception light beam, and an evaluation unit for determining the distance on the basis of a propagation time of the emission and reception light beams. The reception light beam may arise as a result of reflection of the emission light beam at the object. The light receiver may have a reception optical unit comprising a first lens element and a pinhole diaphragm. A light-impermeable element may shade a central region of the reception optical unit in such a way that the reception light beam is incident in the form of a light ring on the pinhole diaphragm. A second lens element, which is substantially hat-shaped in cross section, is arranged between the first lens element and the pinhole diaphragm.
