This method involves evaluating the impact of amplitude and phase modulations of the propagating wavefro... Study on phase function in Monte Carlo transmission characteristics of poly-disperse aerosol [作者：Bai, L; Wu, ZS; Tang, SQ; Li, M; Xie, PH; Wang, SM,期刊：OPTICAL ENGINEERING, 页码：16002-16002 , 文章类型： Article，,卷期：2011年50-1] Henyey-Greenstein (H-G) phase function is typically used as an approximation to Mie phase function and its shortcomings have been discussed in numerous papers. But the judicious criterion of when the H-G phase function w... Toward a two-dimensional barcode with visual information using perceptual shaping watermarking in mobile applications [作者：Liu, JC; Shieh, HA,期刊：OPTICAL ENGINEERING, 页码：17002-17002 , 文章类型： Article，,卷期：2011年50-1] Traditional two-dimensional (2-D) barcodes, such as the QR code and PDF417, do not carry visual information. This work proposes a visually meaningful 2-D barcode (or 2-D image code) that carries not only hidden informati... Improved motion compensation using neighboring pixels and motion vector refinement [作者：Seo, JH; Kim, DY; Lee, YL,期刊：OPTICAL ENGINEERING, 页码：17003-17003 , 文章类型： Article，,卷期：2011年50-1] The H.264/AVC standard utilizes temporal prediction tools to obtain a good coding performance by reducing temporal redundancy between frames. However, because H.264/AVC does not efficiently encode video sequences that ha... Local surface model-based deinterlacing algorithm [作者：Park, SJ; Jeong, J,期刊：OPTICAL ENGINEERING, 页码：17004-17004 , 文章类型： Article，,卷期：2011年50-1] We present an efficient deinterlacing method via mathematical modeling of the neighbor pixels in the local region. The local surface model is designed using the quadratic equation having two-dimensional coordinate variab... Lyapunov exponent of chaos generated by acousto-optic modulators with feedback [作者：Ghosh, AK; Verma, P,期刊：OPTICAL ENGINEERING, 页码：17005-17005 , 文章类型： Article，,卷期：2011年50-1] Generation of chaos from acousto-optic modulators with an electronic feedback has been studied for several years. Such chaotic signals have an important application in providing secure encryption in free-space optical co... Multimodal biometric method that combines veins, prints, and shape of a finger [作者：Kang, BJ; Park, KR; Yoo, JH; Kim, JN,期刊：OPTICAL ENGINEERING, 页码：17201-17201 , 文章类型： Article，,卷期：2011年50-1] Multimodal biometrics provides high recognition accuracy and population coverage by using various biometric features. A single finger contains finger veins, fingerprints, and finger geometry features; by using multimodal... Reflections and Resolutions [作者：Driggers, RG,期刊：OPTICAL ENGINEERING, 页码：10101-10101 , 文章类型： Article，,卷期：2011年50-1] Performance evaluation of visible-light transceiver for peripheral interface [作者：Shin, H; Park, J; Song, S; Park, S; Lee, K; Jung, DK; Lee, Y,期刊：OPTICAL ENGINEERING, 页码：10501-10501 , 文章类型： Article，,卷期：2011年50-1] We examine the practicability of the visible-light communication (VLC) transceiver for bidirectional high-speed and short-range communications. A visible-light peripheral interface could be a novel approach, visualizing ... New family of reflective spectrometers [作者：Romoli, A; Simonetti, F; Gambicorti, L; Marchi, AZ,期刊：OPTICAL ENGINEERING, 页码：13001-13001 , 文章类型： Correction，,卷期：2011年50-1] Three kinds of spectrometers based on off-axis Schmidt and Schmidt-Cassegrain cameras are presented; they have been used for several instruments studies, mainly for European Space Agency and Agenzia Spaziale Italiana. Bo... Vibroacoustic launch analysis and alleviation of lightweight, active mirrors [作者：Cohan, LE; Miller, DW,期刊：OPTICAL ENGINEERING, 页码：13002-13002 , 文章类型： Editorial Material，,卷期：2011年50-1] Lightweight, active, silicon carbide mirrors can increase the capability of space-based optical systems.
