　　Influence of insulator layer width on profile and propagation properties of symmetric surface plasmon polariton ( SPP) mode,which is excited through a dipole embedded in Si02 layer of Au/Si02/Au structure in metal-insulator-metal (MIM) waveguide,has been investigated.The electric field intensity horizontal as well as vertical profiles and propagation properties of symmetric SPP mode with changing Si02 layer width have been analyzed.The decay width is 17 nm.The symmetric SPP mode has a propagation length along Si02 /Au interface that depends on Si02 layer width.Its maximal value is 0.61μm with Si02 layer width of 100 nm.These values provide a theoretical reference for designing a high-performance SPP source using Au/SiO2/Au structure.

高聚光效率的太阳光抽运ND:YAG激光器
太阳光抽运式激光器将非相干的太阳光直接转化成相干的激光.既可以提高转换效率、节省能源,又可以使得整个装置简化.由于太阳光功率密度达不到直接抽运激光器的需求,所以需要高效的聚光系统,来实现抽运激光器所需的阈值要求.本文利用菲涅尔透镜和锥型场镜组成的高效聚光系统,使太阳光可以更高效的耦合进入抽运腔,抽运nd：YAG 晶体.通过模拟得到聚光系统收集的太阳光,聚光比达到104,增大了抽运率,产生更高的激光

多光束傅里叶望远镜的移频设计
多光束傅里叶望远镜对运动的深空暗目标快速成像有着独特的优势,但光学、电学、机械、软件等未突破的关键技术制约着其发展.本文根据傅里叶望远镜的成像原理和GoIombruIer[1],分析选取了多光束成像下每束光的移频量,并依据声光移频器的工作原理设计了符合系统要求的声光移频器.结果表明,采用GoIombruIer下,31束光系统下的最大相对移频量为7.47 MHz,设计的声光移频器通光孔径为8mm、全

基于自适应半径搜索的图像感兴趣区域自动检测
图像中的感兴趣区域是重要性较高并被优先关注的部分。传统的自底向上视觉关注模型利用固定半径的圆形描述感兴趣区域信息，检测精度较低。提出一种新的基于自适应半径搜索的图像感兴趣区域自动检测算法。新算法首先提取图像的颜色、亮度和方向特征，生成多尺度视觉显著图；然后计算全局显著度阈值，得到视觉注意焦点搜索结束的条件；最后在感兴趣区域描述阶段引入自适应半径搜索机制，获得感兴趣区的准确信息。实验结果表明，新算法
