AN account of the recognised methods of investigating the spherical aberration of the eye is given by Tscherning, “Rapports presentés au Congrès international de Physique réuni à Paris en 1900,” tome ...

High-performance nanophotonic devices require extreme depth-to-diameter ratios, which are notoriously difficult to fabricate. Towards this goal, scientists in China developed a novel technique ...

The fascinating history of super speed lenses and why the world's 'fastest' lens was actually a German joke!

The Tecnis PureSee extended depth of focus IOL provides good distance and intermediate vision, according to a real-world study presented at the American Society of Cataract and Refractive Surgery ...

Abstract: Optical aberration is a ubiquitous degeneration in realistic lens-based imaging systems. Optical aberrations are caused by the differences in the optical path length when light travels ...

Abstract: Adversarial domain adaptation has been an effective approach for learning domain-invariant features by adversarial training. In this paper, we propose a novel adversarial domain adaptation ...
