Abstract / Description of output

The storage, transfer and readout of large volumes of photon timing data are key challenges in the design of SPAD dToF imagers, especially if high frame rates, and long ranging distances are to be achieved. This paper describes an imager with partial histogramming units in each pixel that automatically scan, detect and track peaks. Output data rates are reduced further by subbin resolution peak extraction and smart readout modes which only show pixels presenting salient information.
