    • A dual mode optical magnifier system (22) including a plurality of multi-order diffractive optical elements (24) having at least one reflective, refractive and conventional diffractive surface formed thereon, that in combination are operable between a low magnification virtual image display mode (26) and a high magnification virtual image display mode (28). The multi-order diffractive optical elements (24) include a plurality of zones defined by P.times.2.pi., where P is an integer. The use of multi-order diffractive optical elements (24) enables the elements (24) to be very planar and compact in form so as to be incorporated into portable electronic equipment (40 and 60) such as cellular telephones, pagers, smart card readers (20), computers, or the like, while enabling the desired magnification level to be achieved.
    • 一种双模光学放大镜系统(22),包括多个衍射光学元件(24),多个衍射光学元件(24)具有形成在其上的至少一个反射,折射和常规衍射面,其组合可在低倍率虚拟图像显示模式 26)和高倍率虚拟图像显示模式(28)。 多级衍射光学元件(24)包括由Px2i1定义的多个区域,其中P是整数。 使用多级衍射光学元件(24)使得元件(24)能够在形式上非常平坦和紧凑,以便被结合到便携式电子设备(40和60)中,例如蜂窝电话,寻呼机,智能卡读卡器 (20),计算机等,同时实现期望的放大级别。

    • A system for dynamically steering a light beam alters the path of a light beam using refraction. The light beam passes through multiple layers of optically transparent elastic material. Electrodes are attached to the bottom and top surfaces of the optically transparent layers. Voltages applied to the electrodes cause the optically transparent layers to deform. This deformation causes a change in the angle at which the light beam intercepts the surfaces of the optically transparent layers. The light beam is refracted based upon the angle of intercept and the index of refraction of the optically transparent layers. The direction of travel of the light beam can thus be controlled by varying the voltages across the electrodes.
    • 用于动态地转向光束的系统利用折射来改变光束的路径。 光束通过多层光学透明的弹性材料。 电极附着在光学透明层的底表面和顶表面上。 施加到电极的电压导致光学透明层变形。 这种变形导致光束截取光学透明层的表面的角度的变化。 基于截取角度和光学透明层的折射率折射光束。 因此,可以通过改变电极两端的电压来控制光束的行进方向。
