摘要： Some embodiments of the invention relate to a method for measuring spatial points with a laser scanner. The method may include: scanning multiple spatial points on an object; determining coordinates of the respective spatial point, determining a close range about a central spatial point with at least two spatial points whose angle coordinates are in a defined angular space adjacent to those of the central spatial point; aggregating coordinates of the spatial points in the specific close range; and replacing coordinates of the central spatial point by aggregating coordinates of the spatial points in the specific close range. In some embodiments, the laser scanner forms the origin of the coordinates, and the coordinates comprise a distance and at least one angle.

摘要： Some embodiments of the invention may relate to a rangefinder, in particular for a laser scanner, laser tracker, profiler, theodolite, or a total station. In a special embodiment of the invention, the light source of the rangefinder—provided for the emission of pulsed light signals—is configured here as an optical fiber amplifier (e.g. an EDFA, i.e. erbium-doped fiber amplifier) which is optically pumped by a superluminescent diode (SLD) operated in a pulsed manner.

摘要： An electro-optical distance meter and a distance measuring method, wherein a distance to a target is measured based on runtime by means of radiation pulses, which are emitted at a pulse rate. Received radiation pulses are digitized by means of sampling, wherein the sampling rate is set in dependence on the pulse rate, wherein a digitized signal is generated on the basis of sampling over the reception signals of a plurality of received radiation pulses.

摘要： A measuring appliance for performing distance measurements to an object, with an optical transmitter channel, an optical reception channel, a reference light path and an evaluation device, wherein the optical transmitter channel comprises a transmitter unit and an optical outlet element and the optical reception channel comprises an optical inlet element and a reception unit. The measuring appliance facilitates distance measurements over a measurement light path to the object and back again and over a reference light path. An attenuation device renders a desired signal attenuation attainable in the reference light path. The reference light path is laid out in such a way that it receives laser measurement radiation prior to the passage through the optical outlet element, guides said laser radiation without contact with the surroundings to the attenuation device and forwards an attenuated portion to the reception unit through the optical inlet element.

摘要： Some embodiments of the invention relate to a time measurement circuit for an incoming signal. In some embodiments, the time measurement circuit has a comparator stage, for generating a comparator output signal depending on a fulfillment of a criterion by the incoming signal, wherein exceeding or falling below a threshold value is defined as the criterion. Furthermore, a digitization stage is provided, for sampling, which is performed at a defined sampling rate, of an input signal fed to the digitization stage and converting it into digital data containing sampled values for the input signal, and an evaluation unit for determining a chronological location for the incoming signal by evaluating the digital data.
