    • A full color electronic display device using two liquid crystal light valve image forming sources and having two optical paths is suitable for use in projection or direct view display applications. The two-path LCLV device generates two separate, spatially coherent color images which are combined by additive spatial superposition to produce a single, full-spectrum, composite color image. One image is composed from a spectral band of light from the long (red) and medium (green) wavelength regions of the visible light spectrum, and is formed by a liquid crystal image forming source having a high resolution which determines the effective spatial resolution of the final image. The second image is composed from a spectral band of light from the short (blue) wavelength region of the visible light spectrum, and is formed by a liquid crystal image forming source having a resolution less than that of the red and green image, thereby producing a brighter blue light image. These two optical paths and their properties are nominally matched to the characteristics of the chromatic and luminance processing channels of the human visual system. The device produces bright, sharp, and high resolution full-color images using a relatively simple, more easily aligned optical system. The composite image may be either directly viewed or optically projected using a conventional projection lens assembly onto an intermediate viewing surface. Several embodiments of the two-path liquid crystal light valve color display are described herein, each possessing specific features and advantages over existing electronic color displays.
    • 使用两个液晶光阀图像形成源并具有两个光路的全色电子显示装置适用于投影或直视显示应用。 双路LCLV设备产生两个单独的空间相干的彩色图像,其通过加性空间叠加组合以产生单个全光谱复合彩色图像。 一个图像由来自可见光谱的长(红)和中((绿))波长区域的光谱的光谱带组成,并且由具有高分辨率的液晶成像源形成,其确定有效空间分辨率 最后的形象。 第二图像由来自可见光谱的短(蓝色)波长区域的光的光谱带组成,并且由具有小于红色和绿色图像的分辨率的液晶成像源形成,从而产生 一个更亮的蓝光图像。 这两个光路及其性质名义上与人类视觉系统的色彩和亮度处理通道的特性相匹配。 该设备使用相对简单,更易于对准的光学系统产生明亮,清晰和高分辨率的全色图像。 合成图像可以使用常规投影透镜组件直接观看或光学投影到中间观察表面上。 这里描述了双路液晶光阀彩色显示器的几个实施例,每个具有比现有的电子彩色显示器更具体的特征和优点。

    • An analyzer includes a flow cell having a flow channel through which a sample passes. A light source excites at least a first particle type in the sample in one or more excitation region(s), and a detector detects light emitted by the excited particle. A spatial filter defines detection regions, wherein light emitted by the particle is transmitted to the detector, and interspersed shielded regions, wherein such light is at least partially blocked from reaching the detector. The light emitted by the excited particle has a response time τ1, and the sample may also contain a component that is excited by the light source and that has a response time τ2

    • A full color display is disclosed having a high efficiency light source optically coupled by a light coupling lens array to the active matrix of pixel elements of an image forming means such as a transmissive liquid crystal light valve. The light source is comprised of a patterned matrix of individual, primary colored visible radiation emitters, such as individual phosphor elements, arranged in a manner suitable for the human eye to integrate the individual primary colored lights into a single mixture color. The light coupling lens array collects substantially all of the light rays emitted from each primary colored light emitter and focuses them on a respective one of the transparent electrodes in the active matrix, as a real image smaller than the size of the electrode. A suitable light coupling lens array is a gradient index lens array, a multiple layer, two dimensional array of microlenses functionally analogous to an array of strip lenses, or a microlens array. A twisted nematic liquid crystal cell may be used in the image forming means to achieve a high contrast display. Use of the light coupling lens array to collect and focus the light rays from the light source permits the focused light to pass through an entrance polarizer with minimal scattering or divergence, and then through the respective transparent electrode in the active matrix unobscured by the opaque pixel interconnect elements. More efficient use of a larger percentage of the light from the light source in this manner results in the formation of a bright, high contrast, full color image.
    • 公开了一种全色显示器,其具有通过光耦合透镜阵列光耦合到诸如透射型液晶光阀的图像形成装置的像素元件的有源矩阵的高效光源。 光源包括单独的初级着色可见辐射发射器(例如单独的磷光体元件)的图案化矩阵,其以适于人眼的方式布置,以将单独的主要着色光整合为单一混合颜色。 光耦合透镜阵列基本上收集从每个主要着色光发射器发射的所有光线,并将其聚焦在有源矩阵中的相应一个透明电极上,作为小于电极尺寸的实像。 合适的光耦合透镜阵列是梯度折射率透镜阵列,多层,微透镜的二维阵列,功能上类似于带状透镜阵列,或微透镜阵列。 可以在图像形成装置中使用扭转向列型液晶单元,以实现高对比度显示。 使用光耦合透镜阵列来收集和聚焦来自光源的光线允许聚焦光以最小的散射或发散方式通过入射偏振器,然后通过由不透明像素遮挡的有源矩阵中的相应透明电极 互连元件。 以这种方式更有效地利用来自光源的更大百分比的光导致形成明亮的高对比度全色图像。
