Title:
LASER RADAR AND AUTOMOBILE
Document Type and Number:
WIPO Patent Application WO/2024/066524
Kind Code:
A1
Abstract:
The present application relates to the technical field of radars, and provides a laser radar and an automobile. The laser radar comprises a laser transmitter, a bevel galvanometer, a polygon mirror, and a laser receiver. The bevel galvanometer comprises a first reflecting surface and a second reflecting surface which are arranged at an included angle, and a normal vector of the first reflecting surface and a normal vector of the second reflecting surface are divergent. By arranging the bevel galvanometer, an included angle between an incident echo light ray and a mirror surface of the polygon mirror can be increased, and the effective projection area of an echo signal is increased, so that the echo signal strength and the energy utilization rate are improved, and the long-distance detection range is increased. In other words, a smaller optical aperture can be used under the condition of the same range, so that the size of the polygon mirror is reduced, and the wind resistance and the power consumption are reduced. The automobile provided in the present application comprises the laser radar, so that the automobile also correspondingly has the beneficial effects.
