AI Technical Summary

Technical Problem

Existing optical lenses are difficult to miniaturize, have large aberrations, are incompatible with the chip's CRA, have small apertures, and poor temperature performance, resulting in insufficient image quality, especially in automotive applications.

Method used

A specific lens combination is used, including lenses with negative optical power, positive optical power and aspherical lenses. By designing the shape and spacing of the lenses, the light path is optimized to achieve miniaturization and high resolution, while high refractive index lens materials and cemented lenses are used to improve image quality.

Benefits of technology

It achieves miniaturization of optical lenses, reduction of aberrations, matching of CRA chips, improvement of imaging quality and thermal stability, and high resolution capability suitable for automotive environments.
