AI Technical Summary
In existing lens designs, periodic arrangement methods lead to structured artifacts, while non-periodic arrangement methods lack adaptive optimization capabilities, resulting in poor surface uniformity and uneven microstructure distribution.
The lens arrangement method using the Fermat spiral golden angle offset is adopted. By establishing a geodesic polar coordinate system and combining Voronoi spatial subdivision and pre-distortion compensation mechanism, the golden angle and scaling constant are adaptively adjusted to optimize the lattice distribution and achieve a highly uniform arrangement of microstructures on the lens surface.
It achieves high uniformity and isotropic distribution of microstructures on the curved surface of the lens, reduces edge density deviation, and ensures uniformity of visual quality and optical performance.
