Curvature‐Driven, One‐Step Assembly of Reconfigurable Smectic Liquid Crystal "Compound Eye" Lenses. Issue 9 (3rd May 2015) - Serra, Francesca
Abstract A self‐assembly of microlenses on a curved interface can be obtained by pinning smectic liquid crystals around a micropillar with appropriate boundary conditions. This hierarchical structure of microlenses, with variable focal lengths from a few micrometers to a few tens of micrometers, is similar to an insect's compound eye; the lenses are reconfigurable with temperature and sensitive to light polarization.
