1. A light detection and ranging (LiDAR) scanning system, comprising:
one or more light sources configured to provide one or more light pulses; and
a beam steering apparatus optically coupled to the one or more light sources to receive the one or more light pulses;
the beam steering apparatus comprising a light beam steering device and a reflector having a plurality of reflective surfaces,
wherein the light beam steering device is configured to direct the one or more light pulses to the reflector,
wherein the reflector is configured to redirect, upon receiving the one or more light pulses from the light beam steering device, the one or more light pulses to a field-of-view, and
wherein a combination of the reflector and the light beam steering device, when moving with respect to each other, is configured to:
scan the one or more light pulses both vertically and horizontally to illuminate an object within the field-of-view, and
receive return light formed based on the illumination of the object within the field-of-view, and
direct the return light to a detector,
and wherein the light beam steering device is configured to oscillate between two end vertical positions to obtain multiple scanlines in-between.
