    • In illustrative implementations of this invention, multi-path analysis of transient illumination is used to reconstruct scene geometry, even of objects that are occluded from the camera. An ultrafast camera system is used. It comprises a photo-sensor (e.g., accurate in the picosecond range), a pulsed illumination source (e.g. a femtosecond laser) and a processor. The camera emits a very brief light pulse that strikes a surface and bounces. Depending on the path taken, part of the light may return to the camera after one, two, three or more bounces. The photo-sensor captures the returning light bounces in a three-dimensional time image I(x,y,t) for each pixel. The camera takes different angular samples from the same viewpoint, recording a five-dimensional STIR (Space Time Impulse Response). A processor analyzes onset information in the STIR to estimate pairwise distances between patches in the scene, and then employs isometric embedding to estimate patch coordinates.
    • 在本发明的说明性实现中,瞬时照明的多路径分析被用于重建场景几何图形,甚至是从相机遮挡的对象。 使用超高速摄像系统。 它包括光传感器(例如,在皮秒范围内精确的),脉冲照明源(例如飞秒激光)和处理器。 相机发出非常短暂的光脉冲,撞击表面并弹跳。 根据所采取的路径,部分光线可能在一次,两次,三次或更多次弹跳后返回相机。 光传感器捕获每个像素的三维时间图像I(x,y,t)中的返回光反弹。 相机从相同的角度拍摄不同的角度样本,记录五维STIR(空间时间脉冲响应)。 处理器分析STIR中的发作信息以估计场景中的斑块之间的成对距离,然后使用等距嵌入来估计贴片坐标。

    • A method is provided for sharing a display. The method includes displaying periodically a first image sequence on the display in synchronicity with a first signal, and displaying periodically a second image sequence on the display in synchronicity with a second signal. The method also includes selecting by a user the first image sequence for viewing, and shuttering periodically a set of goggles for the user in synchronicity with the first signal. A method is provided for sharing a display. The method includes displaying periodically a private image sequence on the display in synchronicity with a first signal, and displaying periodically a non-private image sequence on the display. In the method, the private image sequence and the non-private image sequence combine to form a public image sequence on the display. A system is provided for sharing a display.

    • There is provided a system for detecting electromagnetic radiation and displaying images produced thereby. The system comprises an imaging device in a first housing, a first rotatable base element carrying an array of input elements which, when rotating together with this base define a surface on which the image is disposed. Rotation of the base element causes the input elements to scan the image, each scanned image point being converted into a video signal which, via a transmission and coupling device is fed to an image recorder and/or display. The system further comprises a second rotatable base element mounted in a second housing and carrying an array of output elements receiving, via a transmission and coupling device, the video signals from the input elements. The rotating output elements which are adapted to convert these video signals into light signals, create the impression of a continuous output image.
