ELECTRICALLY TUNABLE MICROLENS ARRAY FORMED BY PATTERN POLYMERIZATION OF PHOTOPOLYMERIZABLE MIXTURES CONTAINING LIQUID CRYSTALS

摘要

An electrically tunable microlens array. The array is formed by pattern photopolymerization of photoreactive mixtures comprising a polymerizable material and liquid crystals; wherein the photopolymerization is characterized by the interaction of multiple-wave mixing. The liquid crystals are contained as droplets in regions between the polymerized material.
