Application of high-resolution large aperture wide-angle lenses in advanced automotive vision systems
The lens design in this article is primarily for detecting the road conditions ahead of a vehicle, featuring a Wide-angle lens. The design uses the Sony IMX490 sensor for development. The lens offers a maximum field of view of 155 degrees and a horizontal view of 120 degrees, with the key feature being its F1.6 large aperture design. The MTF (Modulation Transfer Function) standard for this design is 1/2 frequency (80 lp/mm), with MTF Center > 60%, 0.5 Field > 50%, and 0.8 Field > 40%. The lens has passed various tests and currently meets legal regulations and safety standards. It also demonstrates good manufacturability and is suitable for mass production.
