AI Technical Summary

Technical Problem

Existing lidar lenses are insufficient to achieve high resolution, failing to meet the high-precision signal detection requirements of automotive autonomous driving assistance systems.

Method used

An optical lens was designed, comprising four lenses. By controlling parameters such as the focal length ratio and radius of curvature of the lenses, especially the focal length ratio of the second and third lenses within the range of 2.32≤|F2/F3|≤5.02, and combining this with the use of plastic aspherical lenses, light deflection and aberration correction are optimized, thereby improving resolution.

Benefits of technology

It achieves high resolution, enhances the distortion correction capability of the edge field of view, improves the imaging performance and miniaturization of the optical lens, and has good thermal performance and temperature compensation capability.
