  • Patent number: 9846234
    Abstract: The invention relates to a method of configuring a laser scanner, as well as to a configuration object for the method.
    Type: Grant
    Filed: December 11, 2014
    Date of Patent: December 19, 2017
    Assignee: SICK AG

  • Patent number: 9383200
    Abstract: A laser scanner (10) detects and determines distances of objects comprises a light transmitter transmitting light in a plurality of consecutive individual pulses. A rotatable deflection unit (18) for the periodical deflection of the transmission light beam (16) into the monitoring zone (20) and an angular measurement unit (30) generates angular position signals (62) in dependence on an angular position of the deflection unit (18). An evaluation unit (32) identifies a received pulse associated with an object from a histogram (110) taken from a histogram memory (32a, 32b) to determine the distance of the object by means of a light propagation method. The histogram (110) is collected over a time interval which is associated with the angular position signal (62). In this connection at least two histogram memories (32a, 32b) are provided in order to collect a first histogram and a second histogram in overlapping time intervals.

  • Patent number: 8643843
    Abstract: A method for estimating a degree of contamination of a front screen of an optical detection apparatus is provided comprising the steps: Transmitting a plurality (p) of transmission radiation pulses into a detection zone; generating a reception signal for each transmission radiation pulse including a plurality (q) of sampled values, a sampled value indicating the intensity of the received back radiation of the transmission pulse after a predefined time interval from the transmission of the transmission radiation pulse; generating an averaged reception signal having a plurality (q) of sampled values from the plurality of reception signals, with those respective sampled values of the reception signals being added which were determined at mutually corresponding points in time to determine a sampled value of the averaged reception signal; generating at least one front screen contamination value by evaluating an amplitude value and/or a measured peak shape value of the averaged signal.
