本文讨论了目前在彩色电视和立体成像中应用的一种选择性掩模器件--视差栅栏。给出了一个简单的历史，以及它的工作原理和几何关系。描述了在每个孔径中使用两个或更多个图像元素并利用最大图像面积的各种系统。结果还表明，非平面和非平行排列是可能的，平面势垒表面可以耦合到非平面像面。此外，透镜可以取代机械类型的障碍物，从而产生更省光的系统。文中给出了公式，并讨论了其在多色电视管中的具体应用。
The parallax barrier, which is a type of selective masking device now being applied in color television and in stereoscopic imagery, is discussed. A brief history along with the principle and geometric relationship underlying its operation is given. Various systems employing two or more image elements per aperture and utilizing the maximum image area are described. It is also shown that nonplanar and nonparallel arrangements are possible, and that plane barrier surfaces may be coupled to nonplanar image surfaces. Furthermore, lenses may replace the mechanical-type barriers resulting in a more light-efficient system. Formulae are presented and specific applications to multiple-color television tubes are discussed.
