Abstract
The present disclosure describes a system and method for LiDAR scanning. The system includes a light source configured to generate one or more light beams; and a beam steering apparatus optically coupled to the light source. The beam steering apparatus includes a first rotatable mirror and a second rotatable mirror. The first rotatable mirror and the second rotatable mirror, when moving with respect to each other, are configured to: steer the one or more light beams both vertically and horizontally to illuminate an object within a field-of-view; redirect one or more returning light pulses generated based on the illumination of the object; and a receiving optical system configured to receive the redirected returning light pulses.

1-26. (canceled)
A light detection and ranging (LiDAR) system for use with a vehicle, comprising:
- a transmitter comprising:
- a plurality of semiconductor based light emitters configured to generate light energy, wherein the transmitter is configured to direct the generated light energy along a plurality of different angles, the combination of the plurality of different angles forming at least a part of a vertical angle range and a horizontal angle range of a field-of-view (FOV) of the LiDAR system;
- a receiver configured to receive light energy reflected from an object within the FOV of the LiDAR system;
- a first mirror and a second mirror, wherein the first mirror is configured to redirect light energy passing between the transmitter and the second mirror, and to redirect light energy passing between the second mirror and the receiver.
A vehicle comprising a plurality of light detection and ranging (LiDAR) devices, wherein at least one of the plurality of LiDAR devices comprises:
- a transmitter comprising:
- a plurality of semiconductor based light emitters configured to generate light energy, wherein the transmitter is configured to direct the generated light energy along a plurality of different angles, the combination of the plurality of different angles forming at least a part of a vertical angle range and a horizontal angle range of a field-of-view (FOV) of the each LiDAR device;
- a receiver configured to receive light energy reflected from an object within the FOV of the each LiDAR device;
- a first mirror and a second mirror, wherein the first mirror is configured to redirect light energy passing between the transmitter and the second mirror, and to redirect light energy passing between the second mirror and the receiver.
