Abstract: The invention divides the lens focusing process into two or more surfaces that incorporate multiple curved axial optic elements on each surface. The axial optics may be manufactured by molding, machining, or by suspended film. If suspended film is used, then both sides of an optic may have a suspended film that is transparent. Alternatively, one side of the suspended film optic may use a reflective film.

Abstract: The present invention is a broadband projection-receiving surface that can function as a projection screen. This surface can, even in strong ambient light, provide high gain, prevent glare and speckle, provide high contrast, preserve of gray-scale linearity, provide a uniformity of brightness, provide rapid angular cut-off, preserve polarization, and provide the ability to function over a large spectral range. These achievements result from a production method that utilizes purposeful partitioning of the material processes used in sub-wavelength morphology (finish) from the processes used to make super-wavelength morphology (figure).

Abstract: A controlled-depth matrix layer structure is formed by floating a plurality of geometric shapes in a solidifiable liquid, then solidifying the liquid to entrap the plurality of geometric shapes in a layer. Multiple layers of liquid may be used, one or more of which may be solidifiable, so long as the sum of displaced masses of all the layers is greater than the mass of the geometric shapes, thereby causing the geometric shapes to float. The resulting structure after solidification of the solidifiable layer is a solidified layer interconnecting the plurality of geometric shapes, wherein each of the plurality of geometric shapes is within the solidified layer a specified percentage. The geometric shapes are preferably of different sizes, and may be spheres, hemispheres, or other suitable shapes, and may be hollow, solid, transparent or reflective.

Abstract: A fluid column projection apparatus and method provide a unique optical effect by providing a plurality of scoops that direct fluid into a hollow chamber. The fluid preferably contains one or more types of light-scattering material. The fluid exits the hollow chamber in a manner that projects the fluid to a considerable distance past the hollow chamber. The hollow chamber may be lit, or an external light source may illuminate the fluid, thereby providing a unique and pleasing optical effect in the form of a column of light.

Abstract: A surface containing a plurality of individually-addressable encoded images comprises an array of curved specular reflectors. Reflectance modifying treatment is applied to a first region of at least one of the curved specular reflectors, such that beamable energy that is directed towards the array is viewable from a first subset of the curved specular reflectors only under a first set of viewing conditions. Reflectance modifying treatment is applied to a second region of at least one of the curved specular reflectors, such that beamable energy that is directed towards the array is viewable from a second subset of the curved specular reflectors only under a second set of viewing conditions.
