The study of Fresnel lens in twisted-nematic liquid crystal fabricated by Sagnac interferometer
碩士 === 國立中山大學 === 物理學系研究所 === 105 === This study presents a focusing efficiency and focal length tunable Fresnel lens with liquid crystals fabricated by a Sagnac interferometer. When the Fresnel-pattern green beam, formed by the Sagnac interferometer, is irradiated on the azo-dye doped liquid-crysta...
