    摘要： A method and apparatus for producing and viewing stereoscopic images through the use of a color coded image whereby the desired depth or distance is based upon the color of the portion of the image being viewed. Therefore the parts of the image which are to appear distant are colored red whereas the parts of the image to appear in the foreground are colored blue with the middle ground or intermediate distances being colored green or yellow. The color coded image is viewed through a prism glass constructed so that blue light which passes through the prism is bent toward a sharper angle than red light. Because the apex of the prism before each eye points toward the nose or center of the glasses the eyes must then turn more inward to see a blue object than to see a red object even though they are in actuality in the same plane on the display. This leads to brain to interpret, by means of parallax, that the blue image is closer and the red image is more distant unless the parallax is greatly contradicted by other depth clues such as relative size, position and perspective. In a preferred form, a double prism is used for each eye in order to eliminate single prism problems such as visual disorientation and eye strain.

    摘要翻译： 一种用于通过使用彩色编码图像来产生和观看立体图像的方法和装置，由此所需的深度或距离基于所观看的图像的部分的颜色。 因此，要显示远处的图像部分是红色的，而出现在前景中的图像部分是蓝色的，中间的地面或中间的距离是绿色或黄色的。 彩色编码图像通过棱镜玻璃来观察，棱镜玻璃被构造成使得穿过棱镜的蓝光比红光弯曲成更锐利的角度。 因为每个眼睛之前的棱镜的顶点指向眼镜的鼻子或中心，所以眼睛然后必须向内转，才能看到一个蓝色的物体，而不是看到一个红色的物体，尽管它们实际上在显示器的同一平面上。 这导致大脑通过视差来解释蓝色图像更接近，红色图像更远，除非视差与诸如相对大小，位置和透视度的其他深度线索相矛盾。 在优选的形式中，每个眼睛使用双棱镜，以消除诸如视觉迷失方向和眼睛疲劳的单一棱镜问题。

    摘要： A periscopic rear view optical system for vehicles in which an image of a rearward objective is reflected downwardly from a rooftop mirror through a prismatic device constructed as a transparently faced housing filled with a liquid suitable for the optical path to be within the critical angle at the desired reflective faces for reflection of the image to the driver of the vehicle. A modification of the device includes adjustable prism faces to accommodate different driver heights, with the spatial dimension variations produced by the adjustment effecting a vertical movement of the device.

    摘要： A variable light filter comprises a fluid filled cavity having opposed transparent walls with a prismatic member movable in the cavity for varying the thickness of a light modifying fluid interposed in the optical path between the transparent walls, the control for the prismatic member including an element movable in the cavity without causing any displacement of the total volume of said fluid.

    摘要： The invention relates to a lens, comprising a container (100) defining a volume (V) which is filled with a transparent liquid (2), wherein the container (10) comprises a transparent and elastically deformable membrane (20) and a rigid member (30), wherein the membrane (20) and the rigid member (30) delimit said volume (V), and a lens shaping element (200) that contacts the membrane (20) and defines an area (21) of said membrane (20), which area (21) has an adjustable curvature for adjusting the focal length of the lens (1). According to the invention, the lens (1) is configured to compensate a thermal expansion of the liquid (2) and/or a change of the refractive index of the liquid (2) due to an increased temperature of the liquid (2) in order to reduce an unwanted thermally induced change of the focal length of the lens (1).

    摘要： An electromagnetic wave cloaking device is described. The device may include a plurality of first-type dielectric units, a plurality of second-type dielectric units, and a plurality of four kinds of spacers. The dielectric units and the spacers are arranged such that an electromagnetic wave incident unto the cloaking device can be refracted within the device and around a cloaking area surrounded by the device.
