Abstract

Embodiments of the disclosure provide transmitters for light detection and ranging (LiDAR). The transmitter includes a laser source, a light collimator, and a beam shifter. The laser source is configured to provide a native laser beam. The light collimator is configured to collimate the native laser beam to form an input laser beam transmitting along a lateral direction. The beam shifter is configured to shift the input laser beam along a vertical direction perpendicular to the lateral direction by a displacement to form an output laser beam. The output laser beam and the input laser beam are parallel to each other.
