A flash LIDAR apparatus includes emitter units configured to emit optical signals over a field of view, and detector pixels configured to output detection signals responsive to light representing the optical signals incident thereon. The detection signals correspond to respective phase offsets relative to a frequency of the optical signals. A circuit is configured to determine component measurements corresponding to the respective phase offsets from the detection signals, and calculate a distance of a target from which the light was reflected based on the detection signals. The distance is corrected for motion of the target based on subsets of the component measurements.
