This way, an axial shear is introduced in the imaging system. Compared to conventional differ... Chandra x-ray optics [作者：Weisskopf, MC,期刊：OPTICAL ENGINEERING, 页码：11013-11013 , 文章类型： Article，,卷期：2012年51-1] Significant advances in science always occur when the state of the art in instrumentation improves dramatically. NASA's Chandra X-ray Observatory represents such an advance. Launched in July of 1999, Chandra is an observ... The Spitzer Space Telescope [作者：Werner, M,期刊：OPTICAL ENGINEERING, 页码：11008-11008 , 文章类型： Article，,卷期：2012年51-1] The Spitzer Space Telescope, which has operated very successfully since 2003 in its unique Earth-trailing solar orbit, is NASA's Great Observatory for infrared astronomy. We provide a quick overview of the optical charac... High thermal expansion optical component machined by ion beam figuring [作者：Xie, XH; Hao, Y; Zhou, L; Dai, YF; Li, SY,期刊：OPTICAL ENGINEERING, 页码：13401-13401 , 文章类型： Article，,卷期：2012年51-1] Ion beam figuring (IBF) Technology to fabricate optical materials with a high thermal expansion coefficient, such as BK7, we were aware that the thermal effect is a troublesome problem that generates high thermal stress.... Feature space-based human face image representation and recognition [作者：Xu, Y; Fan, ZZ; Zhu, Q,期刊：OPTICAL ENGINEERING, 页码：17205-17205 , 文章类型： Article，,卷期：2012年51-1] We propose a novel face recognition method that represents and classifies face images in the feature space. It first assumes that in the feature space the test sample can be well expressed by a linear combination of the ... Using a 1.2 GHz bandwidth reflective semiconductor optical amplifier with seeding light by 64-quadrature amplitude modulation orthogonal frequency division multiplexing modulation to achieve a 10-gbits/s upstream rate in long-reach passive optical network access [作者：Yeh, CH; Chen, HY; Chow, CW; Wu, YF,期刊：OPTICAL ENGINEERING, 页码：15004-15004 , 文章类型： Article，,卷期：2012年51-1] We use a commercially available 1.2 GHz bandwidth reflective semiconductor optical amplifier (RSOA)-based optical network unit (ONU) to achieve 10-gbits/s upstream traffic for an optical orthogonal frequency division mul... Design and demonstration of a tiled-grating frame [作者：Zhang, JW; Chen, W; Xie, N; Zhou, Y; Zhou, H; Wang, X; Jing, F; Zhang, XM,期刊：OPTICAL ENGINEERING, 页码：13007-13007 , 文章类型： Article，,卷期：2012年51-1] Development of a phased-array-grating compressor is a crucial issue for high-energy ultrashort pulse petawatt lasers. To achieve tiled array gratings and increase stability of tiled-grating frames, a new tiled grating fr...
