AI Technical Summary

Technical Problem

The light convergence ability of traditional lidar lenses is poor, which affects the detection accuracy of lidar, especially when the lens is used as a receiving mirror, it will affect the focus quality of the retracted wave.

Method used

A lidar lens is designed, and the lens body forms a first light-through surface between the flared end and the closed end as an aspherical surface and the second light-through surface is a convex surface or plane. Combined with specific radius of curvature and coefficient parameters, the light conduction path is optimized to correct the spherical difference and the intelligent difference.

Benefits of technology

It improves the light convergence capability of lidar lenses, improves the detection accuracy and echo focus quality of lidar, and is suitable for miniaturized lidar systems.

Abstract

The present application relates to the technical field of intelligent household appliances. Disclosed are a LiDAR lens (100), a LiDAR (200) and a cleaning robot. The LiDAR lens (100) comprises a lens body (110), wherein the lens body (110) comprises a tapered end and a flared end; a first light-transmitting surface (111) is formed between the flared end and the tapered end of the lens body (110); a second light-transmitting surface (112) is formed at the flared end; and as the first light-transmitting surface (111) is an aspheric surface, the second light-transmitting surface (112) is a convex surface or a flat surface, and light is conducted by means of the first light-transmitting surface (111) and the second light-transmitting surface (112), and the lens body (110) can simultaneously correct spherical aberration and coma aberration, so that the LiDAR lens (100) has better light convergence capability, and can improve the focusing quality of an echo received by the LiDAR (200), thereby improving the detection precision when the LiDAR lens (100) is applied to the LiDAR (200).
