    • An electrically driven device for surface enhanced Raman spectroscopy includes a first electrode, a substrate positioned proximate to the first electrode, a plurality of cone shaped protrusions formed integrally with or on a substrate surface, a Raman signal-enhancing material coated on each protrusion, and a second electrode positioned relative to the first electrode at a predetermined distance. Each of the protrusions has a tip with a radius of curvature ranging from about 0.1 nm to about 100 nm. The second electrode is positioned relative to the first electrode such that the electrodes together produce an electric field when a voltage bias is applied therebetween. The electric field has a field distribution that creates a stronger field gradient at a region proximate to the tips than at other portions of the substrate.
    • 用于表面增强拉曼光谱的电驱动装置包括第一电极,靠近第一电极定位的基板,与基底表面一体地形成的多个锥形突起,涂覆在每个突起上的拉曼信号增强材料,以及 相对于第一电极以预定距离定位的第二电极。 每个突起具有具有约0.1nm至约100nm范围的曲率半径的尖端。 第二电极相对于第一电极定位,使得当在其之间施加电压偏置时,电极一起产生电场。 电场具有场分布,其在靠近尖端的区域处产生比在衬底的其它部分更强的场梯度。

    • A surface enhanced Raman spectroscopy system includes a surface enhanced Raman spectroscopy substrate and a laser source configured to emit light within a spectrum of wavelengths toward a predetermined species on or near the surface enhanced Raman spectroscopy substrate. The system further includes a set of filters positioned to be in optical communication with light scattered after the laser light interacts with the predetermined species. Each of the filters in the set is respectively configured to pass scattered light within a different predetermined narrow band of wavelengths. The system also includes a plurality of photodetectors, where each photodetector is positioned adjacent to a respective one of the filters in the set and is configured to output a signal if the scattered light passes through the respective one of the filters. The set of filters is targeted for detection of characteristic peaks of the predetermined species.
    • 表面增强拉曼光谱系统包括表面增强拉曼光谱基板和激光源,该激光源被配置为向表面增强拉曼光谱基板上或附近的预定物质发射波长光谱的光。 该系统还包括一组滤光器,其被定位成在激光与预定物质相互作用之后与散射的光光通信。 集合中的每个滤光器分别被配置成使不同预定的窄波段内的散射光通过。 该系统还包括多个光电检测器,其中每个光电检测器被定位成与集合中的相应一个滤光器相邻,并且被配置为如果散射光通过相应的一个滤光器则输出信号。 该组滤波器用于检测预定种类的特征峰。

    • In a particular embodiment, a see-through display includes a screen having transparent layer of material with a front side and a back side. At least one plurality of shaped louver members is disposed between the front side and the back side. The plurality of the louver members allow transmission of a fraction of light through the screen with minimum scattering within a range of incident angles. The plurality of the louvers also redirect image signal light from an image source into a range of angles centered about a normal to the screen. The louver members combine the image signal light with the light emitted from background objects located on the backside of the screen. The background image light is transmitted through the display screen with minimal scattering. For embodiments providing two sets of louver members, the image signal light may be redirected to observers on either side of the screen, such that the observers may see each other as well as the intended image.
    • 在特定实施例中,透视显示器包括具有前侧和后侧的透明材料层的屏幕。 至少一个成形百叶窗构件设置在前侧和后侧之间。 多个百叶窗构件允许一定数量的光在入射角的范围内以最小的散射透过屏幕。 多个百叶窗还将来自图像源的图像信号光重定向到以屏幕垂直为中心的范围内。 百叶窗构件将图像信号光与位于屏幕背面的背景物体发出的光组合。 背景图像光通过显示屏以最小的散射传播。 对于提供两组百叶窗构件的实施例,图像信号光可以被重定向到屏幕两侧的观察者,使得观察者可以看到彼此以及期望的图像。
