Title

Adaptive-Focus Lenses

Abstract

Researchers have demonstrated various approaches for constructing practical, compact, adaptive-focus lenses. Nematic liquid crystals (LC) are rod-like molecules, which, when aligned in a homogeneous cell, their long axes are approximately parallel to each other. An LC lens with a hole patterned electrode can be easily fabricated. Polymer stabilization is an interesting approach for making an LC lens. Researchers have made various efforts to develop adaptive liquid lenses based on elastic membranes, in order to improve its structure and performance. electrowetting lenses are another effort, which can be switched over a long period without any degradation. Dielectric lenses have a large focus power change and fast response time during focus change. Of all the lenses, liquid crystal lenses are the most suitable for making small aperture lenses, because it is based on the gradient refractive index.
