    摘要： A system and method are described for achieving a high efficiency, full color display using color sensitive lenses such as holographic lenses. A lens assembly is composed of discrete lens elements (1, 2, 3) which are sensitive to different wavelengths bands of light. Each lens element (1, 2, 3) focuses input light within its waveband onto a corresponding target area, and generally transmits input light outside of its waveband. A separate target area (R, G, B) is provided for each lens element, whereby incoming light is divided into its constituent colors. The separate color stripes (R, G, B) may then be operated upon to produce a desired display. For incoming light which is to be divided into n different wavebands and directed onto separate target areas each having an area A, the area of each lens element is approximately nA, and each lens overlaps the next adjacent lens by an area approxmately equal to (n-1)A. By generally transmitting rather than absorbing light outside the band of each lens element, the assembly achieves a high degree of both efficiency and resolution. Specific applications to various types of flat-panel displays and light valves are disclosed, as well as preferred fabrication techniques for the holographic lenses.

    摘要翻译： 描述了一种系统和方法，用于实现使用诸如全息透镜的彩色敏感透镜的高效率全色显示。 透镜组件由对不同波长的光带敏感的分立透镜元件（1,2,3）组成。 每个透镜元件（1,2,3）将其波段内的输入光聚焦到相应的目标区域上，并且通常在其波段外部传输输入光。 为每个透镜元件提供单独的目标区域（R，G，B），由此入射光被分成其组成颜色。 然后可以对单独的颜色条纹（R，G，B）进行操作以产生期望的显示。 对于被分成n个不同波段并被引导到各自具有区域A的单独目标区域的入射光，每个透镜元件的面积大约为nA，并且每个透镜与下一相邻透镜重叠大约等于（n -1）A。 通过大致透射而不是吸收每个透镜元件的带外的光，组件实现了高度的效率和分辨率。 公开了各种类型的平板显示器和光阀的具体应用，以及用于全息透镜的优选制造技术。

    摘要： A variable-angle, wide-angle illuminator is disclosed, one embodiment being a small-gauge, variable-angle illumination surgical system comprising: a light source for providing a light beam; an optical cable, optically coupled to the light source for receiving and transmitting the light beam; a handpiece, operably coupled to the optical cable; an optical fiber, operably coupled to the handpiece, wherein the optical fiber is optically coupled to the optical cable to receive and transmit the light beam; an optical assembly, optically coupled to a distal end of the optical fiber, for receiving the light beam and providing the light beam to illuminate a surgical field; and a cannula, operably coupled to the handpiece and optical assembly, for housing and directing the optical assembly to illuminate a selected area, such as a surgical site. The optical assembly can comprise, for example, a fiber/polymer-dispersed-liquid-crystal (“PDLC”) diffuser optically coupled to an optical needle or a nested compound parabolic concentrator (“CPC”) cone. In the PDLC diffuser/needle embodiment, the fiber can be a standard endo-illuminator optical fiber with 0.50 NA or similar value. The light beam from the light source is emitted from the distal end of the optical fiber and provided to the PDLC diffuser for further transmission. The degree of diffusion of the light beam at the PDLC diffuser can be electrically controlled and can be varied from no diffusion to very high degree of diffusion. After passing through the PDLC diffuser, the light beam is provided to a needle or fiber, such as a glass needle or fiber, that transmits the light beam to the surgical site in the eye.

    摘要： In certain embodiments, a system may include a housing, one or more lenses, and a scanning system. The housing has an interior region. A lens is disposed within the interior region and transmits a light beam. The scanning system is disposed within the interior region and comprises a number of scanning cells, where each scanning cell comprises an electro-optical (EO) material. The scanning system performs the following for a number of iterations to yield a spot pattern: receive one or more voltages and electrically steer the light beam with the EO material from a current direction to a next direction in response to the voltages.
