The optical operating principles of the LC lens in a human eye system are introduced and the optical principle of the polarization independent of the double-layered LC lens is investigated. The polarization dependency, image quality and the response time of the double-layered LC lens are measured. The continuously tunable-focusing properties of the LC lenses are more practical in applications for different visional conditions of people. The concept in this paper can also be extensively applied to imaging systems, and projection systems, such as cameras in cell phones, pico projectors, and endoscopes.Item type:Item, Spectral Variations in Selective Reflection in Cholesteric Liquid Crystals Containing Opposite-Handed Chiral Dopants(2014-06-13) ;Liu, Yu-Jen ;Wu, Po-Chang ;Lee, Wei ;交大名義發表影像與生醫光電研究所The optical properties of cholesteric liquid crystal (CLC) containing a nematic host dispersed with a binary chiral dopant were investigated. The binary dopant was composed of a right-hand twist (RT) chiral agent and a left-hand twist (LT) chiral agent whose helical twisting power was much smaller than that of the RT one. With a fixed content of the RT additive, we found that the sample redshifts in central wavelength of the selective reflection as the concentration of the LT agent increases, presumably due to the increasing helical pitch caused by the racemic effect. Some other interesting results including the dopant-content and temperature dependence of the optical properties are addressed.Item type:Item, Electrically Tunable Liquid Crystal Lenses and Applications(2014-06-13) ;Lin, Yi-Hsin ;Chen, Hung-Shan ;Chen, Ming-Syuan ;交大名義發表光電工程學系Electrically tunable liquid crystal (LC) lenses have been studied for over 30years. Three main problems of LC lenses hinder the applications: 1) the paradox between the response time and tunable focusing range, 2) polarization dependency, and 3) large aperture size for ophthalmic lenses. In this paper, we introduce the two mode switching method of the LC lenses to solve the paradox of the LC lenses. The basic optical principles for designing polarization independent LC lenses are discussed and several polarizer-free LC lenses we developed are reviewed. Several applications of LC lenses are also introduced, including auto-focusing imaging systems, auto-focusing projection systems, optical zoom systems, endoscopic systems, solar cells, ophthalmic lenses for myopia-presbyopia.Item type:Item, The growth mechanisms of graphene directly on sapphire substrates by using the chemical vapor deposition(2014-06-14) ;Lin, Meng-Yu ;Su, Chen-Fung ;Lee, Si-Chen ;Lin, Shih-Yen光電工程學系Uniform and large-area graphene films grown directly on sapphire substrates by using a low-pressure chemical vapor deposition system are demonstrated in this paper. The evolution process and the similar Raman spectra of the samples with different growth durations have confirmed that the continuous graphene film is formed by graphene flakes with similar sizes. The layer-by-layer growth mechanism of this approach is attributed to the preferential graphene deposition on sapphire surfaces. The etching effect of H-2 gas is demonstrated to be advantageous for the larger graphene grain formation. The smooth surface of substrates is also proved to be a key parameter for continuous graphene film formation with better crystalline quality.
