摘要： An optoelectronic sensor for detecting three-dimensional image data from a monitored zone is provided that has an illumination unit for illuminating the monitored zone with modulated transmitted light, a light receiver for a simultaneous light reception of the transmitted light remitted by objects in the monitored zone at at least two locations at a mutual distance corresponding to a first resolution pattern, and a control and illumination unit that is configured to determine times of flight from properties of the modulated and remitted transmitted light and to detect three-dimensional data in a second resolution pattern finer than the first resolution pattern by at least one measurement repetition with a light reception from at least two other locations shifted with respect to the first resolution pattern.

摘要： A distance-measuring optoelectronic sensor (10) for detecting and determining a distance of an object (16) in a monitoring area (14), the sensor (10) having a light transmitter (12) for transmitting a transmission signal, a light receiver (18) for generating a reception signal and a control and evaluation unit (24) configured to determine a light time of flight from the reception signal and, from that, the distance of the object (16), wherein the control and evaluation unit (24) is further configured to transmit at least one periodically modulated pulse as a transmission signal, to determine a reception time of the pulse in the reception signal and a phase offset of the modulation between transmission signal and reception signal in a neighborhood of the reception time and to determine the distance of the object (16) from the reception time and the phase offset.

摘要： A sensor (10) for determining a distance of an object (18), the sensor (10) transmitting a plurality of transmission pulses via a transmitter (12), accumulating reflected reception pulses (102) in a histogram (110), and determining therefrom a time of flight to the object (18). The sensor (10) has a control (24) for processing and outputting measurement values. Measuring unit (22) and control (24) are mutually connected to pass measurement values and to set a timing for the control (24) via a clocked synchronizing signal in that the control (24) executes a control cycle each time when receiving the synchronizing signal. An output rate of measurement values is programmable by the measuring unit (22) setting a smallest base clock and passing an updated measurement value to the control (24) after a multiple of the base clock corresponding to the programmed output rate.

摘要： A light receiver (22) is provided having a plurality of avalanche photodiode elements (24) that can each be biased above a breakdown voltage by a bias voltage and can thus be operated in a Geiger mode, wherein the avalanche photodiode elements (24) form a plurality of groups, and having a control unit (30) to change the sensitivity of the avalanche photodiode elements (24) of a respective group. In this respect, the control unit (30) is configured to respectively change the sensitivity of the avalanche photodiode elements (24) of a group at at least one point in time assigned to the group, with different points in time being assigned to the groups.
