Quantum-wire conductance manipulating by asymmetric quantum dot-molecules 不对称量子点分子操纵量子线电导
A. Rostami, H. Rasooli, A. Ghanbari, S. Zabihi, F. Janabi-Sharifi
The electronic conductance at zero temperature through a quantum wire with side-attached asymmetric quantum dot-molecules (as a scatter system) is theoretically studied using the non-interacting Anderson tunneling Hamiltonian method. We show that the asymmetric configuration of QD-scatter system strongly impresses the amplitude and spectrum of quantum wire nanostructure transmission characteristics. It is shown that whenever the balanced number of chains-quantum dots in one molecule is substituted by unbalanced scheme, the number of forbidden mini-bands in quantum wire conductance increases to the sum of the number of quantum dots in two chains and thus the QW-nanostructure electronic conductance contains rich spectral properties due to appearance of the new anti-resonance and resonance points in spectrum. Considering the suitable inner gap between QD-chains in one molecule or outer gap between QD-molecules, can strengthen the amplitude of new resonant peaks in QW conductance spectrum. The proposed asymmetric-QD scatter system idea in this paper opens a new insight on designing quantum wire nanostructures for given electronic conductance.
采用非相互作用的安德森隧穿哈密顿方法,从理论上研究了具有侧附的非对称量子点分子(作为散射系统)的量子线在零度下的电子电导。研究表明,量子散射系统的不对称结构对量子线纳米结构的振幅和光谱传输特性有着强烈的影响。结果表明,当一个分子的平衡链量子点数被不平衡方案取代时,量子线电导率中的禁止小带数增加到两个链量子点数的总和,从而由于谱中新的反共振和共振点的出现而使量子线纳米结构的电子电导率具有丰富的光谱性质。考虑合适的分子内量子点链间隙或分子外量子点链间隙,可以增强量子点电导谱中新共振峰的振幅。本文提出的非对称量子点散射系统思想为设计给定电子电导的量子线纳米结构开辟了新的思路。

Dynamic phase measurement by clustering method 聚类法动态相位测量
Y. H. Huang, S. Hung, Y. Chen, L. Liu, S. Ng
Phase measurement is a key step in quantitative optical metrology. While phase shifting technique is widely applied for accurate and reliable static or semi-static phase measurement, Fourier and wavelet transforms are often employed for high speed dynamic phase measurement. In our previous papers, the authors had proposed an alternative clustering method for dynamic phase measurement. The proposed method utilizes the phase clustering effect and the prior knowledge of the speckle field to extract the deformed phase map from one single deformed speckle pattern. The clustering method, however, may fail at area with abundant noise and large phase gradient. In this paper, we improve the clustering method by incorporating an advanced phase filtering methods for wrapped phase filtering. The reconstructed wrapped phase map is with very good quality and ready for phase unwrapping with any simple unwrapping algorithms. The basic ideas and the implementation approach will be described in details. Several examples based on shearography and holographic interferometry will be presented. Comparisons between the proposed method and phase shifting method will be made. The results demonstrate the accuracy and robustness of the integrated dynamic phase extraction method. The integrated phase retrieval method proposed here has great potential to simplify optical setup for dynamic phase measurement.
相位测量是定量光学计量的关键步骤。相移技术被广泛应用于精确可靠的静态或半静态相位测量,而傅里叶变换和小波变换则常用于高速动态相位测量。在我们之前的文章中,作者提出了一种动态相位测量的替代聚类方法。该方法利用相位聚类效应和散斑场的先验知识,从单个变形的散斑图中提取变形的相位图。然而,在噪声较大、相位梯度较大的区域,聚类方法可能失效。在本文中,我们改进了聚类方法,将一种先进的相位滤波方法用于包裹相位滤波。重构后的相位图具有很好的质量,可以用任何简单的展开算法进行相位展开。本文将详细描述其基本思想和实现方法。本文将介绍几个基于剪切术和全息干涉术的例子。将所提出的方法与相移法进行比较。结果表明,该方法具有较高的精度和鲁棒性。本文提出的综合相位恢复方法在简化动态相位测量的光学设置方面具有很大的潜力。

Enlarging effective mode area of photonic crystal fibers using defected core structures 利用缺陷芯结构扩大光子晶体光纤的有效模面积
A. Rostami, A. Ghanbari, H. Soofi, F. Janabi-Sharifi
In this paper a new strategy to design large mode area photonic crystal fibers with relatively small hole pitches is presented and employed to design fibers with effective mode areas larger than 70µm2 at λ=1.55µm with hole pitch Λ=2.5µm. The idea is based on insertion of circular defect holes in the core area of an HF7 fiber. It is shown that by precisely adjusting the locations and the diameters of these defect holes, field distribution alters in a way that leads to a larger effective mode area than HF7 fiber itself. The validation of the proposed design is carried out by adopting an efficient full-vectorial finite difference frequency domain method with perfectly matched layers for accurate characterization of photonic crystal fibers. Dispersion characteristics of the designed fibers is also investigated and it is shown that the defect insertion has strong dispersion flattening and lowering attitude that can significantly ease the fiber design task for optical communication transmission systems.
本文提出了一种设计孔径相对较小的大模面积光子晶体光纤的新策略,并利用该策略设计出了λ=1.55µm、孔径Λ=2.5µm处有效模面积大于70µm2的光纤。这个想法是基于在HF7光纤的核心区域插入圆形缺陷孔。结果表明,通过精确调整缺陷孔的位置和直径,可以改变场分布,从而获得比HF7光纤本身更大的有效模面积。采用一种有效的全矢量有限差分频域方法对光子晶体光纤的精确表征进行了验证。对所设计光纤的色散特性进行了研究,结果表明,缺陷插入具有较强的色散平坦化和降低姿态,可以显著减轻光通信传输系统中光纤的设计任务。

Amin Dehghani, Aboozar Moradi, R. Jafari
In this paper we present a numerical three dimensional (3D) simulation of transient heat transfer process in the human eye. A finite element method is applied to obtain the solution of a boundary value problem for a 3D transient heat transfer model in the human eye. The human eye is modeled as a com position of several homogeneous regions. The Ritz method in the finite element method is used for solving heat differential equ ation. Applying the boundary conditions, the heat radiation condition and the Robin condition on the cornea surface of the eye and on the outer part of sclera are used, respectively. Simulation results of two and three dimensional models are compared.

Compensation of repeatable and nonrepeatable disturbances in high NA SIL-based near-field storage systems 高NA sil近场存储系统中可重复和不可重复干扰的补偿
Jung-Gon Kim, N. Park
This paper presents an effective control algorithm to avoid physical contact between the disk and the solid immersion lens (SIL) in near-field (NF) storage systems under dynamic operating conditions such as repeatable and nonrepeatable dist urbances due to disk vibrations and external shocks. In particular, the air-gap distance between the disk and the SIL in the NFR system is less than 50 nm. Therefore, the disk and the SIL must be protected to detect the stable gap error signal (GES) during continuous control operation. In this manuscript, we propose an improved air-gap control system using a narrow-ban d disturbance filter (NBDF), which is an effective control method for enhancing the performance of the system for the rejection of repeatable and nonrepeatable disturbances In addition, we demonstrate an improved air-gap controller using a double disturbance observer (DOB) to improve the anti-shock control performance under external shocks. The double DOB uses a binomial Q filter without additional sensors, which keeps the production cost low. Finally, to evaluate the robustness of the control system with the double DOB, we apply a design method that varies the bandwidth of the Q filter.
本文提出了一种有效的控制算法,以避免近场存储系统在磁盘振动和外部冲击引起的可重复和不可重复的距离扰动等动态运行条件下磁盘与固体浸没透镜(SIL)之间的物理接触。特别是在NFR系统中,磁盘与SIL之间的气隙距离小于50 nm。因此,必须保护磁盘和SIL,以便在连续控制操作过程中检测到稳定间隙误差信号(GES)。在本文中,我们提出了一种改进的气隙控制系统,使用窄禁干扰滤波器(NBDF),这是一种有效的控制方法,可以提高系统对可重复和不可重复干扰的抑制性能。此外,我们还展示了一种改进的气隙控制器,使用双干扰观测器(DOB)来提高外部冲击下的抗冲击控制性能。双DOB使用二项Q滤波器,没有额外的传感器,这使得生产成本低。最后,为了评估双DOB控制系统的鲁棒性,我们采用了一种改变Q滤波器带宽的设计方法。

Yu Qi-feng, Fu Si-hua, Jiang Guang-wen, Lei Zhi-hui
Measurement for ship deformation has been a difficult problem for the global ship building industry and navy equipment rese arches. So far, an effective and mature method to measure the 3-D position and attitude deformation in a long term still remains unavailable. An innovative pose-relay videometric is proposed, and then a pose-relay video-metrics measurement system for ship defo rmation is developed on the basis of principle research and experimental validations. It offers solutions to key technical problems of infrared marker facture and high-precision detection and multi-cameras synchronization and control, etc. Accordingly, sea trials were carried out, and reasonable, long-time, and continuous 3-D data of position and attitude deformations between the ship head and the stern were acquired. The experiments have implied the great applicability of the proposed method in the deformation measurement and long-term monitoring of ships and similar large structures.

Line scanning confocal microscopy with the use of cross structured illumination 使用交叉结构照明的线扫描共聚焦显微镜
MyoungKi Ahn, Taejoong Kim, Youngduk Kim, D. Gweon
In this paper, we propose new SI method, the cross SI method that improves the lateral resolution and the image acquisition speed. The cross SI pattern is generated by using the 2-D diffractive grating. The acquisition of a total of 6 raw images shortens the image acquisition time. The cross structured illumination confocal microscope (CSICM) is combined with the cross SI pattern generation optics and the line scanning confocal microscope. Performances of the conventional and the cross SI are compared by the analysis of the modulation transfer function. As a result, the cro ss SI method shows similar resolution to conventional SI method. The CSICM has the two times enhanced lateral resolution than the conventional microscope, the optical sectioning ability and the fast image acquisition speed.

This paper describes the non-contact Man-Machine in terface based on the face orientations. The real-time image of the operator's face was observed by the USB camera and the changes in the darkness area of the both nostrils were utilized for recognition of the face orientations. When the operator faced to up and downward, the darkness areas of both nostrils were increased and decreased, respectively. On the other hand, the difference between two nostril areas could be caused in cases where the face was turn to the side. Here, these characteristics were reflected to the recognition of the face orientations. The developed interface was applied for the operation of the electrical wheelchair.
本文介绍了基于人脸定向的非接触式人机界面。通过USB摄像头实时观察操作者面部图像,利用双鼻孔暗区变化进行人脸方位识别。当操作者面朝上和面朝下时,两个鼻孔的暗区分别增加和减少。另一方面,当脸转向一边时,两个鼻孔区域之间的差异可能会引起。在这里,这些特征被反映到人脸方向的识别上。开发的接口应用于电动轮椅的操作。
