However, it has been found...

Holographic polymer dispersed liquid crystal enhanced by introducing urethane trimethacrylate [作者：Nataj, NH; Mohajerani, E; Jashnsaz, H; Jannesari, A,期刊：APPLIED OPTICS, 页码：697-703 , 文章类型： Article，,卷期：2012年51-6] This work characterizes holographic polymer dispersed liquid crystals (HPDLC) composite material based on a new monomer, urethane trimethacrylate, by fabricating switchable diffraction grating. The highest diffraction ef... Projection approach to complexity reduction in tomographic alignment of extremely large telescopes [作者：Piatrou, P; Chanan, G,期刊：APPLIED OPTICS, 页码：704-712 , 文章类型： Article，,卷期：2012年51-6] We describe a complexity reduction approach intended to solve the tomographic alignment problem for the Thirty Meter Telescope by means of its alignment and phasing system (APS) with little loss of information. This appr... High-efficiency holograms fixed in lithium niobate after recording using a digital fringe stabilization system [作者：Arizmendi, L; Ambite, EJ,期刊：APPLIED OPTICS, 页码：713-719 , 文章类型： Article，,卷期：2012年51-6] We used a digital feedback control loop system to produce reproducible fixed volume transmission holograms of high diffraction efficiency. Different strategies were investigated to obtain holograms of good quality and th... Rotation angle measurement based on white-light interferometry with a standard optical flat [作者：Yun, HG; Kim, SH; Jeong, HS; Kim, KH,期刊：APPLIED OPTICS, 页码：720-725 , 文章类型： Article，,卷期：2012年51-6] We propose a simple white-light interferometric method of measuring a one-dimensional rotation angle with use of an optical plane parallel plate of standard refractive index. The phase change of the interference pattern ... Thermal-structural modeling of polymer Bragg grating waveguides illuminated by a light emitting diode [作者：Kim, KJ; Bar-Cohen, A; Han, BT,期刊：APPLIED OPTICS, 页码：726-734 , 文章类型： Article，,卷期：2012年51-6] This study reports both analytical and numerical thermal-structural models of polymer Bragg grating (PBG) waveguides illuminated by a light emitting diode (LED). A polymethyl methacrylate (PMMA) Bragg grating (BG) wavegu... Mueller matrix roots depolarization parameters [作者：Noble, HD; McClain, SC; Chipman, RA,期刊：APPLIED OPTICS, 页码：735-744 , 文章类型： Article，,卷期：2012年51-6] The Mueller matrix roots decomposition recently proposed by Chipman in [1] and its three associated families of depolarization (amplitude depolarization, phase depolarization, and diagonal depolarization) are explored. D... Quantitative security evaluation of optical encryption using hybrid phase- and amplitude-modulated keys [作者：Sarkadi, T; Koppa, P,期刊：APPLIED OPTICS, 页码：745-750 , 文章类型： Article，,卷期：2012年51-6] In the increasing number of system approaches published in the field of optical encryption, the security level of the system is evaluated by qualitative and empirical methods. To quantify the security of the optical syst... Improved white-light interferometry on rough surfaces by statistically independent speckle patterns [作者：Wiesner, B; Hybl, O; Hausler, G,期刊：APPLIED OPTICS, 页码：751-757 , 文章类型： Article，,卷期：2012年51-6] White-light interferometry (WLI) on rough surfaces is based on interference from individual speckles. The measurement uncertainty of WLI is limited by a random shift of these individual interference patterns. The statist... Current measurement by Faraday effect on GEPOPU [作者：Correa, N; Chuaqui, H; Wyndham, E; Veloso, F; Valenzuela, J; Favre, M; Bhuyan, H,期刊：APPLIED OPTICS, 页码：758-762 , 文章类型： Article，,卷期：2012年51-6] The design of an optical current sensor to be used in a pulsed power generator is presented. The current sensor is based on the polarization rotation by the Faraday effect. GEPOPU is a pulsed power generator, 110kA, 120 ... Super deep 3D images from a 3D omnifocus video camera [作者：Iizuka, K,期刊：APPLIED OPTICS, 页码：763-770 , 文章类型： Article，,卷期：2012年51-6] When using stereographic image pairs to create three-dimensional (3D) images, a deep depth of field in the original scene enhances the depth perception in the 3D image. The omnifocus video camera has no depth of field li... Rangeability extension of fiber-optic low-coherence measurement based on cascaded multistage fiber delay line [作者：Li, SG; Li, XW; Zou, WW; Chen, JP,期刊：APPLIED OPTICS, 页码：771-775 , 文章类型： Article，,卷期：2012年51-6] We demonstrate a simple method to extend the measurable fiber length with a fiber-optic low-coherence technique.
