1. A light detection and ranging (LiDAR) scanning system, comprising:
a light source configured to generate a plurality of light pulses;
a power controller comprising a plurality of power switches, wherein the plurality of power switches comprises circuitry of a first power switch and circuitry of a second power switch, the first power switch and the second power switch are controllable to select respective different power levels for at least two respective consecutive light pulses of the plurality of light pulses;
a first mirror and a second mirror,
wherein at least one of the first mirror or the second mirror is configured to move about a respective axis that does not overlap with a respective normal axis of the first mirror or the second mirror, and
wherein the first mirror and the second mirror, when moving with respect to each other, are configured to:
scan the plurality of light pulses both vertically and horizontally to a field-of-view, and
redirect one or more returning light pulses generated based on the scanned light pulses; and
a receiving optical system configured to receive redirected returning light pulses.
