Abstract: A display system enables viewing a stereo pair of images without any special eyewear. In one embodiment an array of micro-lens elements are mounted in front of a pixel-based image display. Lens elements in the micro-lens array can have differing fixed optical properties and in one embodiment the micro-lens array can have differing focal lengths to provide flexibility as to the location of a viewer, reduced optical distortion, and more comfortable viewing due to balanced horizontal and vertical resolution.

Abstract: A light source in which a lamp aperture is arranged to illuminate a large panel provided with a reflective surface by having light rays from the aperture pass through a trough wherein such rays are changed so they are all substantially at angles greater than the critical angle necessary for total internal reflection. Light reflected from the panel is emitted through a window with the aid of light scatterers.

Abstract: A fluorescent light source of small physical size and high brightness is provided by making the vitreous envelope of cylindrical configuration and providing it with an inserted partition assembly that is coated with phosphor and longitudinally extends from the hermetically sealed end of the envelope to its flat end wall or face. The partition assembly preferably comprises a series of radiallyextending sheet metal panels that divide the envelope interior into a series of interconnected sectors that define a discharge channel which forces the discharge to follow a retroverted path through the envelope. One end of the partition assembly is seated against the flat end wall of the envelope and its opposite end is seated in keyed interlocked relationship with a disc-like support member that is held in place by the lead-in conductors and has channels which receive the ends of the partition panels.

Abstract: A method for separating isotopes in which a selected isotope is first ionized in a partially bounded region and then driven toward the boundary by space charge electric fields. Radial electric fields, which accelerate movement of the charged particles towards the walls of the boundary, are generated by charge separation associated with ambipolar diffusion of the particles in the plasma column. Selective photoexcitation leads to the preferential ionization of the isotopic component to be separated from the gas mixture. The resulting altered gas mixture component concentrations in the central region and periphery of the bounded area flow from the system through different output channels.
