Liquid-crystal microlens with a beam-steering function

Not Accessible

Your library or personal account may give you access

Abstract

A novel beam-steering device that makes use of a nematic liquid crystal (LC) is proposed and demonstrated. The beam-steering function is attained with a LC microlens with a divided hole-patterned electrode structure (DE-LC microlens). Optical properties of the DE-LC microlens are investigated and three-dimensional variable-focusing and beam-steering properties are verified experimentally for the first time, to our knowledge.
