    • A stereoscopic television which enables plural observers to simultaneously observe a stereoscopic images includes a color liquid-crystal plate, a monochrome TV display disposed behind the liquid-crystal plate, and a large format lens disposed between the color liquid-crystal plate and the monochrome TV display so as to focuss the observer's image on the screen of the TV display. The color liquid-crystal plate alternately displays stereo-pairs composed of left and right eye perspectives, and the monochrome TV display alternately displays inverted binary images of half face of each oberver. The large format lens distrubutes light emitted from the inverted binary images of half face of each observer to the left and right eyes of each observer through the color liquid-crystal plate, whereby the left and right eye perspectives of the stereo-pairs displayed by the liquid-crystal plate respectively reach the left and right eyes of each observer.

    • A three-dimensional television camera system based on a spatial depth signal and receiver system therefor is disclosed wherein a video depth signal is generated in spatial synchronization with the raster scan of a TV camera viewing a scene. The video depth signal is generated by taking the ratio of the outputs of a pair of spaced apart sensors receiving a reflected laser beam of a laser projector situated between the sensors. The laser projector, sensors, and TV camera are in close proximity to each other. A portion of the energy receiving photocell of each sensor is blocked by a parallax barrier so that a proportion of the reflected laser beam energy is detected and that receipt of energy is angle dependent. By such construction, the depth difference of two points proximate each other is sensed. A continuous video depth signal is outputted in synchrony with the TV camera video signal to the receiver system. The described receiver system employs two TV cathode ray tubes to be viewed stereoscopically, i.e., one for each eye. On CRT operates as in a convention television receiver receiving the TV camera video signal and the other CRT receives the same video signal except the horizontal sweep component is modified by the video depth signal. By such instrumentality, a scene is viewed in three dimensions much like the sell known stereoscope.
    • 公开了一种基于空间深度信号及其接收机系统的三维电视摄像机系统,其中与观看场景的电视摄像机的光栅扫描以空间同步方式产生视频深度信号。 视频深度信号是通过接收接收位于传感器之间的激光投影仪的反射激光束的一对间隔开的传感器的输出的比率而产生的。 激光投影机,传感器和电视摄像机彼此靠近。 每个传感器的能量接收光电池的一部分被视差屏障阻挡,使得检测到反射的激光束能量的一部分,并且能量的接收是取决于角度的。 通过这种结构,感测到彼此靠近的两个点的深度差。 将连续的视频深度信号与TV摄像机视频信号同步地输出到接收机系统。 所描述的接收机系统使用两个TV阴极射线管来立体观察,即每个眼睛一个。 在CRT操作中,如在接收TV摄像机视频信号的公约电视接收机中操作,另一个CRT接收相同的视频信号,除了水平扫描分量被视频深度信号修改。 通过这样的手段,一个场景在三维中被视为非常像销售已知的立体镜。

    • A system for enhancing the resolution of an image comprising a plurality of phase affecting light transmitting objects, preferably plates, disposed in a stack in the light path of the light energy defining an image, each plate having a thickness and being spaced a distance apart from others of the plates. Preferably, a source of radiant energy is provided for irradiating the plates and spaces between the plates in the stack and optionally the image itself to enhance resolution further by creating standing waves that interfere with the light in the light path defining the image. The plates are preferably edge illuminated, and the radiant energy may be visible light, ultraviolet energy or infrared energy, individually or intermixed. The system has application both for enhancing existing images as well as enhancing images during the image storage process.
