Holding time aware differentiated protection method for survivable waveband switching optical networks [作者：Hou, WG; Guo, L; Li, Y; Wu, TF,期刊：OPTICAL ENGINEERING, 页码：125002-125002 , 文章类型： Correction，,卷期：2011年50-12] Due to the number of wavelengths in fibers increasing, the transmission ports consumed in optical cross-connect (OXC) are greatly enhanced. To reduce the complexity and the cost of OXC, waveband switching technology is p... Countermeasure effectiveness against a man-portable air-defense system containing a two-color spinscan infrared seeker [作者：Jackman, J; Richardson, M; Butters, B; Walmsley, R,期刊：OPTICAL ENGINEERING, 页码：126401-126401 , 文章类型： Article，,卷期：2011年50-12] Man-portable air-defense (MANPAD) systems have developed sophisticated counter-countermeasures (CCM) to try and defeat any expendable countermeasure that is deployed by an aircraft. One of these is a seeker that is able ... Spatiotemporal computed tomography of dynamic processes [作者：Kaestner, A; Munch, B; Trtik, P; Butler, L,期刊：OPTICAL ENGINEERING, 页码：123201-123201 , 文章类型： Article，,卷期：2011年50-12] Modern computed tomography (CT) equipment allowing fast 3-D imaging also makes it possible to monitor dynamic processes by 4-D imaging. Because the acquisition time of various 3-D-CT systems is still in the range of at l... People detection method using graphics processing units for a mobile robot with an omnidirectional camera [作者：Kang, S; Roh, A; Nam, B; Hong, H,期刊：OPTICAL ENGINEERING, 页码：127204-127204 , 文章类型： Article，,卷期：2011年50-12] This paper presents a novel vision system for people detection using an omnidirectional camera mounted on a mobile robot. In order to determine regions of interest (ROI), we compute a dense optical flow map using graphic... Multifiber optical bend sensor to aid colonoscope navigation [作者：Kesner, JE; Gavalis, RM; Wong, PY; Cao, CGL,期刊：OPTICAL ENGINEERING, 页码：124402-124402 , 文章类型： Article，,卷期：2011年50-12] A colonoscopy's near-blind navigation process frequently causes disorientation for the scope operator, leading to harm for the patient. Navigation can be improved if real-time colonoscope shape, location, and orientation... Three-phase quadrature spectral matching imager using correlation image sensor and wavelength-swept monochromatic illumination [作者：Kimachi, A; Ando, S; Doi, M; Nishi, S,期刊：OPTICAL ENGINEERING, 页码：127208-127208 , 文章类型： Article，,卷期：2011年50-12] We propose a three-phase spectral matching imager (3PSMI) to realize a novel spectral matching method called quadrature spectral matching (QSM) in real time. The 3PSMI is comprised of the correlation image sensor (CIS) a... Denoising computed tomography imagery using a novel framework [作者：Kozaitis, SP; Mehta, JM; Ponkia, S,期刊：OPTICAL ENGINEERING, 页码：127007-127007 , 文章类型： Article，,卷期：2011年50-12] We denoised computed tomography (CT) imagery using a novel framework.
