摘要： An optical display panel which provides improved viewing contrast for front projection applications, and a method of producing a stacked optical waveguide panel for front projection applications, are disclosed. The optical panel includes a plurality of stacked optical waveguides, wherein each waveguide has a back face and an outlet face at opposing ends of each waveguide, and wherein each waveguide is formed of a core between an opposing pair of cladding layers, and at least one reflector connected to the back face of at least one waveguide, wherein the at least one reflector receives image light incident through at least one waveguide from the outlet face, and wherein the at least one reflector redirects the image light back through the at least one waveguide out of the outlet face. In the preferred embodiment, the outlet face is rendered black by inclusion of black within or between cladding layers. The method includes stacking a plurality of clear strips of plastic, placing a double sided, dark colored adhesive between each strip of plastic, pressing the stack, forming, at two opposite ends of the stack, a back face and an outlet face, and connecting at least one reflector to the back face.

摘要： Alignment of an array of N elements, such as optical fibers, within a preselected tolerance value is obtained using a primary substrate with a plurality of N apertures extending therethrough from a first surface to a second opposing surface. Each aperture, at its narrowest point, has a cross-section that is greater than a cross-section of an element to be inserted therethrough. Each of the elements passes through its corresponding aperture and rests against the same corresponding point and/or sidewall of the aperture so as to result in the desired alignment. A directing arrangement directs the elements toward the primary substrate at a predetermined angle to cause a spring-like action to occur in each of the elements when threaded through its associated aperture for aligning the elements to engage the same corresponding point and/or sidewall of the aperture.

摘要： A light transport device comprises light fibers that individually have predetermined cross sections at one end that may be bundled together to provide a bundled region that terminates in a continuous plane, suitable for light input, that is substantially free of voids and free of non-light-transmitting materials. The other end of the individual light fibers has a cross section that is useful for emission of light from a single fiber. In the absence of non-light-transmitting materials, light propagating in each of the light guides undergoes mixing by being coupled, while traveling in the bundled region, from one light guide to another, thus reducing nonuniformities in the color and intensity of the light emitted by the fibers.

摘要： The percentage fraction of fundamental mode power located in the cladding holes of different holey fibers (PFholes) is shown as a function of wavelength in microns of the fundamental mode (&lgr;). Properties of two groups of holey fibers are shown. The upper group of three curves shows embodiments of the invention with &Lgr;=0.75 &mgr;m and d/&Lgr;=0.6, 0.7 & 0.8 respectively, where d is the hole diameter and &Lgr; the hole spacing or pitch. The lower group of curves, which are almost superimposed on each other, show properties of holey fibers representative of the prior art with &Lgr;=3.2 &mgr;m and d/&Lgr;=0.6, 0.7 & 0.8 respectively. A huge improvement in the mode power present in the holes is evident. In the prior art curves, the mode power fraction is generally less than 1%, whereas with the illustrated embodiments of the invention, holey fibers with 10-40% of the fundamental mode power in the holes are achieved. Generally the holey fiber should be structured such that the wavelength of the guided light &lgr;>2.2&Lgr;. For telecommunications wavelengths, this means that the hole spacing should be smaller than typical in the prior art, i.e. around 1 &mgr;m or less, and the hole diameter should be as large as possible in relation to the hole spacing, preferably d/&Lgr;>=0.6.

摘要： An emissive display may include a faceplate that improves contrast and increases light efficiency in some embodiments. The emissive display may be covered by a plurality of cones that define light pipes between the cones. The cones may be reflective on one surface to reflect outwardly through a microlens. The inside surfaces of the cones may be light absorbing to absorb stray light that would not otherwise be properly emitted from the display.

摘要： An optical display panel which provides improved light intensity at a viewing angle by redirecting light emitting from the viewing screen, and a method of making a light redirective display panel, are disclosed. The panel includes an inlet face at one end for receiving light, and an outlet screen at an opposite end for displaying the light. The inlet face is defined at one end of a transparent body, which body may be formed by a plurality of waveguides, and the outlet screen is defined at an opposite end of the body. The screen includes light redirective elements at the outlet screen for re-directing light emitting from the outlet screen. The method includes stacking a plurality of glass sheets, with a layer of adhesive or epoxy between each sheet, curing the adhesive to form a stack, placing the stack against a saw and cutting the stack at two opposite ends to form a wedge-shaped panel having an inlet face and an outlet face, and forming at the outlet face a plurality of light redirective elements which direct light incident on the outlet face into a controlled light cone.

The light generator is preferably placed parallel to and proximate with the inlet face, thereby allowing for a reduction in the depth of the housing.
