  • Patent number: 9268013
    Abstract: A method for measuring distances of targets by measuring the time of flight of pulses, in particular laser pulses, reflected on those targets, including the steps of; transmitting pulses having a pulse interval which varies according to a modulation signal as transmitted pulses, and concomitantly recording of reflected pulses as received pulses; determining a first series of distance measurement values from times of flight between transmitted pulses and those received pulses which are respectively received within a first time window following each transmitted pulse; determining at least a second series of distance measurement values from times of flight between transmitted pulses and those received pulses which are respectively received within a second time window following each transmitted pulse; and determining that series of distance measurement values which is least affected by the modulation signal as result of the distance measurement.

  • Patent number: 8995577
    Abstract: Apparatus for measurement of the reception time of a pulse in a receiving system, which contains at least one receiving channel with a non-linear transmission response, which receiving channel produces at its output a received signal, having a memory, in which the received signals of reference pulses with a predetermined different amplitude are available as reference signals with respect to a time scale, and having an evaluation device, which is connected to the receiving system and to the memory and compares a received signal with each reference signal with a variant time offset in order to determine that reference signal and that time offset for which the comparison discrepancy is a minimum, and outputs this time offset as the reception time with respect to the time scale.

  • Patent number: 8307705
    Abstract: Method for laser hydrography in which at least one laser beam is emitted from a known location and in a known direction onto the surface of a body of water and through the water onto the bottom of the body of water and measurement points of the water surface and the water bottom in a coordinate system are determined from transit-time measurements of the reflections of the laser beam at the water surface and water bottom, wherein the local inclination of the water surface at an entry point of the laser beam into the body of water is determined from at least three measurement points of the water surface, wherein a local entry angle of the laser beam into the body of water is determined from the local inclination and the known direction of the laser beam, and wherein the measurement point of the water bottom is created as a function of the laser beam direction, the local inclination, and the optical refraction due to the corresponding local entry angle of the laser beam.

  • Patent number: 7697120
    Abstract: A scanning apparatus for use in a scanning optical system comprises a laser transmitter to produce a transmitter beam. This transmitter beam is deviated by a beam scanner, e.g. a tiltable mirror, to produce a pattern of a scanning beam. There are bearings which define first and second axes of rotation perpendicular to each other and intersecting each other in an intersecting point for allowing the beam scanner to scan. In front of the beam scanner is a window of transparent material in the shape of a spherical cap so as to define a central axis and a central point. The central axis intersects the intersecting point of the two other axes, and this common intersecting point coincides preferably with the central point of the sphere of the window.

  • Patent number: 7330242
    Abstract: A system for recording an object space has a opto-electronic distance sensor which uses a signal propagation time method, and a transmitter for transmitting optical, signals, as well as a receiver (E) for receiving optical signals, reflected by objects located in the target space. The system comprises a scanner for deflecting optical axes of the transmitter and receiver (S and E). The optical axes of the transmitter and receiver (S and E) for example, are substantially parallel. An evaluation system determines distance values from the propagation time or phase position of the transmittal optical signals, and the space coordinates of the individual data elements result from the distance values and the beam deflection implemented by the scanner. The system comprises a rotary measurement head mounted on a pillow block, and a mirror system fixed relative to the measurement head, which deflects beams axially incident on the hollow shaft in the radial direction and vice versa.

  • Patent number: 6879384
    Abstract: A process and an apparatus for measuring an object space using an opto-electronic range finder which operates according to a method of determining the time-of-flight of a signal comprise a first measuring step including transmitting optical transmitter signals in form of a beam of a predetermined first divergence angle, receiving optical signals reflected from an object and evaluating a distance value, while scanning the object space. After or before this first take-up step follows a second one wherein reference marks in the object space are taken up with a using an enlarged divergence angle so as to detect reliably the reference marks. The apparatus comprises, accordingly, appropriate devices for varying the divergence angle.
