    Abstract: An optical scanner comprises a light transmitter for transmitting a light beam; a beam deflection unit that is configured to deflect the transmitted light beam in a periodically varying manner with a predefined period duration in order to scan a detection zone; a light receiver for receiving reflected light; and an electronic control device for controlling the beam deflection unit. The electronic control device is configured to automatically increase or decrease the period duration by a difference amount with respect to a nominal value before or during the operation of the optical scanner in order to counteract crosstalk between the optical scanner and a further optical scanner.

    Abstract: A distance-measuring sensor (10) is provided for detecting and determining the distance of objects (18) in a monitored zone comprising a transmitter (12) for transmitting transmitted pulses; a receiver (20) for generating a received signal from the transmitted pulses remitted in the monitored zone; a first comparator unit (36a) for digitizing the received signal with reference to a first threshold; and a control and evaluation unit (30) which is configured to transmit a plurality of transmitted pulses via the transmitter (12), to collect the received signals thereupon generated by the receiver (20) in a histogram and to determine a received time point from the histogram and thus to determine a measured value for the signal transit time from the sensor (10) to the object (18). In this respect, a second comparator unit (36b) is provided for digitizing the received signal with reference to a second threshold, wherein the first comparator unit (36a), the second comparator unit (36b) and the control and evaluation unit (30) are configured to acquire three digital states of a respective section of the received signal with reference to the first threshold and to weight the contributions of the section to the histogram in dependence on the digital state.
