Abstract
A LIDAR system that may include a transmitter and a receiver. The LIDAR system may include a transmitter and a receiver that may include an array of neuromorphic pixels and multiple accumulators. Each neuromorphic pixel may include multiple subpixels, an analog adder and a comparator; wherein for each reception period the analog adder is configured to generate an analog adder signal by adding detection signals from subpixels that are expected to receive at least one received light pulse during the reception period; wherein for each reception period the analog adder signal is indifferent to subpixels that are not expected to receive any received light pulses during the reception period; and wherein the comparator is configured to provide pixel output signals by comparing the analog adder signal to a threshold. The multiple accumulators are configured to add multiple pixel output signals from neuromorphic pixels to provide, for each neuromorphic pixel, an accumulated signal that represents radiations sensed by the neuromorphic pixel during the multiple reception periods.
