    • Several devices for determining a distance of an object a user of an electro-active lens is looking at are presented. Once the distance is determined, the devices may alter the optical power of the electro-active lens to ensure that the object is correctly focused. Optical range finding is a possible means for carrying out this task. An active rangefinder may emit optical radiation from a transmitter directed at the object. The optical radiation may then be reflected off the object. The reflected optical radiation may then be received with an appropriate receiver. The received optical radiation may then be processed by appropriate circuitry to determine a distance to the object. A passive rangefinder works without a transmitter. Instead, an appropriate receiver receives ambient sources of light from the object. The received light may then be processed by appropriate circuitry to determine a distance to the object.
    • 介绍了几种用于确定电激励透镜的用户正在观看的物体的距离的装置。 一旦确定了距离,设备可以改变电激励透镜的光焦度,以确保物体正确聚焦。 光学测距是执行此任务的一种可能手段。 有源测距仪可以发射来自发射器的光辐射,该发射器指向物体。 然后可以将光辐射反射离开物体。 然后可以用合适的接收器接收反射的光辐射。 然后可以通过适当的电路处理接收到的光辐射以确定到物体的距离。 无源测距仪在没有发射器的情况下工作。 相反,适当的接收器接收来自物体的环境光源。 接收到的光然后可以由适当的电路处理以确定到物体的距离。

    • A light steering system including an electro-optic steering assembly operable (300) to provide controllable steering of light rays. In one example, the electro-optic steering assembly (300) includes first (304), second (306) and third (303) electrode layers. An electrically insulating layer (305) can be positioned between the first (304) and second (306) electrode layers. A layer of electro-optic material (301) is positioned between the second (306) and third (303) electrode layers. The first electrode layer (304) is positioned on a first substrate (302) and includes substantially parallel linear electrodes having longitudinal axes orientated in a first direction. The second electrode layer (306) includes substantially parallel linear electrodes having longitudinal axes orientated in a second direction orthogonal to the first direction. A layer of electro-optic material is not provided between the first (304) and second (306) electrode layers.
