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

  • a first light source configured to provide one or more first light pulses; and

    one or more beam steering apparatuses optically coupled to the first light source, each beam steering apparatus comprising a rotatable concave reflector and a light beam steering device, wherein the combination of the light beam steering device and the rotatable concave reflector, when moving with respect to each other, is configured to;

    steer the one or more first light pulses both vertically and horizontally to illuminate an object within a field-of-view,obtain one or more first returning light pulses, the one or more first returning light pulses being generated based on the steered first light pulses illuminating an object within the field-of-view, andredirect the one or more first returning light pulses to one or more receiving optical systems disposed in the LiDAR scanning system.
