1. An array-based light detection and ranging (LiDAR) unit comprising:

  • an array of emitter/detector sets configured to cover a field of view for the unit, each emitter/detector set configured to emit and receive light energy on a specific coincident axis unique for that emitter/detector set; and

    a control system coupled to the array of emitter/detector sets to control initiation of light energy from each emitter and to process time of flight information for light energy received on the coincident axis by the corresponding detector for the emitter/detector set,wherein time of flight information for light energy corresponding to the array of emitter/detector sets provides imaging information corresponding to the field of view for the unit and interference among light energy corresponding to an emitter of the specific coincident axis of an emitter/detector set is reduced with respect to detectors in the LiDAR unit other than the detector of the emitter/detector set corresponding to the specific coincident axis.
