1. A LiDAR (light detection and ranging) system comprising:

  • an emitter that emits a series of emitted light packets over a field of view, each emitted light packet emitted for a cycle duration;

    a detector array having an array of detectors configured to cover the field of view and sample an incoming retroreflected signal portion of an emitted light packet at a pre-determined sampling frequency that generates at least two samples corresponding to the cycle duration of the emitted light packet;

    a processing system configured to analyze the samples from the detector array and detect an objects within the field of view using at least a volumetric analysis of the at least two samples from each detector in the array of detectors corresponding to the incoming retroreflected signal portion of each emitted light packet.
