    • The present disclosure is a novel design of a polarization based stereoscopic display system that efficiently utilizes the optical energy from three primary color solid state light sources of random polarization, combines the three primary colors into a full color beam of a single polarization state to enable passive separation of the two image channels. The high optical energy efficiency is achieved by splitting each primary color light into two orthogonal polarization states. The single polarization state of the combined full color image beam is achieved by employing a spectrally selective light beam combiner or X-cube. By making the optical configuration of sub-module basically identical and sharing a number of optical components among color and image channels, the size and cost is reduced. By compensating the depolarization effect that is introduced by folding mirror(s), the cross talk between the two displayed stereo images is minimized.
    • 本公开是基于偏振的立体显示系统的新颖设计,其有效地利用来自随机极化的三原色固态光源的光能,将三原色组合成单偏振状态的全色光束,以使得被动 分离两个图像通道。 通过将每个原色光分成两个正交偏振状态来实现高光能效率。 通过采用光谱选择性光束组合器或X立方体来实现组合全彩色图像束的单偏振状态。 通过使子模块的光学配置基本相同,并在彩色和图像通道之间共享多个光学部件,减小了尺寸和成本。 通过补偿由折叠镜引入的去极化效果,两个显示立体图像之间的串扰最小化。

    • In embodiments of optical arrangements of a working distance sensor in a fundus camera that can improve the determination of a correct working distance as well as the transverse positioning of the camera a number of near infrared light sources are arranged to project a number of near infrared illumination beams into the visible light illumination path of the fundus camera and a live view of the retina under near infrared illumination is captured and displayed on a monitor. These embodiments of optical arrangements and associated methods will enable an operator to directly determine if there is any undesirable flare or other artifact appearing within a designated region on the infrared retina view as a result of a wrong alignment of the fundus camera with respect to the eye in terms of not only the working distance but also the horizontal and vertical positions. Pattern recognition algorithms can be used to further enhance the positioning sensitivity of the working distance sensor. An additional iris alignment sensor can be added to achieve a coarse alignment and also function as a measure to determine if the dilation of the iris size is sufficient for different mode of fundus imaging.
    • 在眼底照相机中的工作距离传感器的光学布置的实施例中,其可以改善确定正确的工作距离以及相机的横向定位,并且布置多个近红外光源以投射多个近红外照明 光束进入眼底照相机的可见光照明路径,并且在近红外照明下的视网膜的实时图像被捕获并显示在监视器上。 光学布置和相关方法的这些实施例将使得操作者能够直接确定由于眼底照相机相对于眼睛错误对准的结果,在红外线视网膜视图上的指定区域内是否存在任何不期望的耀斑或其他伪像 不仅在于工作距离,还包括水平和垂直位置。 模式识别算法可用于进一步提高工作距离传感器的定位灵敏度。 可以添加附加的虹膜对准传感器以实现粗略对准,并且还用作确定虹膜尺寸的扩张是否足够用于不同的眼底成像模式的措施。

    • A bandwidth adjusting method and a communication node are provided. The adjusting method includes: sending, by an upstream ingress unit, a group of multi-channel parallel basic switch cells in which adjustment signaling is carried to all downstream branch egress units; sending normal signaling when determining that adjustment response statuses returned by all the downstream branch egress units are reception acknowledgment; after receiving the normal signaling by the downstream branch egress unit, adding or removing the basic switch cell into or from a next group of multi-channel parallel basic switch cells according to the adjustment signaling; and adjusting a time slot of an HO ODU sent by the downstream branch egress unit to a downstream node, and instructing the downstream node to adjust the time slot of the HO ODU. Through the method and the communication node, lossless bandwidth adjustment in a point-to-multipoint OTN asymmetric bandwidth carrier system is implemented.
