    • A stereoscopic endoscope employing a single light sensor array and a lenticular lens layer located at a proximal end of the endoscope, a pair of periscopic prisms located at a distal end of the endoscope and an optical relay assembly array located between the pair of periscopic prisms and the light sensor array. One prism of the pair of periscopic prisms receives a right view of an object and another prism of the pair receives a left view of the object. The interpupilar distance (IPD) between the right and left view is substantially large, thereby increasing the resolution of a stereoscopic image which is eventually displayed on a display. Another embodiment includes a set of three light sensor arrays, a light director and three lenticular lens layers. Each light sensor array detects light at a predetermined range of wavelengths (e.g. red, green and blue).
    • 一种使用位于内窥镜的近端的单个光传感器阵列和双凸透镜层的立体内窥镜,位于内窥镜的远端的一对透视棱镜和位于一对透视棱镜之间的光学继电器组件阵列,以及 光传感器阵列。 一对透视棱镜的一个棱镜接收物体的右视图,另一个棱镜接收对象的左视图。 右视图和左视图之间的相邻距离(IPD)基本上大,从而增加最终显示在显示器上的立体图像的分辨率。 另一个实施例包括一组三个光传感器阵列,光导向器和三个双凸透镜层。 每个光传感器阵列检测预定波长范围(例如,红色,绿色和蓝色)的光。

    • A stereoscopic opthalmoscope for producing a stereoscopic image of an eye fundus, the stereoscopic opthalmoscope including a light source, for emitting a light beam, a light deflector, optically coupled with the light source, for deflecting the light beam into an eye, thereby illuminating the eye fundus of the eye, a relay lens, optically coupled with the eye, for receiving light beams reflected from the eye fundus, thereby producing a relayed three-dimensional image of the fundus, and a stereoscopic imaging apparatus, optically coupled with the relay lens, for stereoscopically acquiring the relayed three-dimensional image. The stereoscopic imaging apparatus includes a dual aperture element, a pixel array image detector and a lenticular lens layer, optically coupled with the pixel array image detector. The lenticular lens layer directs a right view scene of the relayed three dimensional image toward a first plurality of pixels of the pixel array image detector and a left view scene of the relayed three-dimensional image toward a second plurality of pixels of the pixel array image detector.
    • 一种用于产生眼底立体图像的立体眼镜,所述立体式眼镜包括用于发射光束的光源,与光源光耦合的光偏转器,用于将光束偏转到眼睛中,从而照亮 眼睛的眼底,与眼睛光学耦合的中继透镜,用于接收从眼底反射的光束,从而产生眼底的中继的三维图像;以及立体成像装置,与中继透镜光学耦合 ,用于立体地获取中继的三维图像。 立体成像装置包括与像素阵列图像检测器光学耦合的双孔元件,像素阵列图像检测器和双凸透镜层。 双凸透镜层将中继的三维图像的右视图场景朝向像素阵列图像检测器的第一多个像素和中继的三维图像的左视场景朝向像素阵列图像的第二多个像素 探测器。
