1. A method of operating an opto-electronic sensor array comprising:

  • directing a plurality of sequential operating light pulses into a monitored region during an activation interval;

    receiving operating light pulses reflected off an object arranged in the monitored region on a spatially resolving receiver unit having a plurality of light-sensitive sensors;

    determining a light intensity of the reflected operating light pulses and synchronously storing the light intensities during the activation interval while the operating light pulses are directed into the monitored region;

    following each activation interval, sequentially transmitting subsets each comprising a plurality of light intensity values to a parallel processor having a corresponding plurality of parallel inputs; and

    parallel processing the plurality of light intensity values of each subset.
