Multizonal mulifocal phase patterns, published in Optics Letters



This computational study explores radially and angularly segmented multifocal patterns. The analysis reveals that angularly segmented (3-4 segments) are optimal patterns, providing more extended depth of focus and higher optical performance than patterns with larger amount of segments, radially concentric patterns, or spherical aberration inducing patterns. The study has been published today in Optics Letters.
