摘要： A reflective film includes interior layers arranged to selectively reflect light by constructive or destructive interference, the layers extending from a first zone to a second zone of the film. The film has a first thickness and the interior layers provide a first reflective characteristic in the first zone; the film has a second thickness and the interior layers provide a second reflective characteristic in the second zone. The difference between the first and second reflective characteristics is not substantially attributable to any difference between the first and second thicknesses, which difference may be zero. Rather, the difference in the reflective characteristics is substantially attributable to reduced birefringence of at least some of the interior layers in one zone relative to the other zone. The film may also incorporate absorbing agents to assist in the manufacture or processing of the film. Related methods and articles are also disclosed.

摘要： A virtual image (VI) device displays an image that appears to lie above or below the plane of the device. A method of manufacturing a VI display device includes calculating an initial VI flux pattern based on an object and then fabricating a substrate having a VI array pattern based on the initial VI flux pattern. A plurality of lenses may then be applied over the VI array pattern. The VI substrate may be static or dynamic, and may show grey scale information. A photomask may be used as an intermediate element in the manufacture of the VI substrate, or may act as the VI substrate itself. A method of producing the initial VI flux pattern includes virtually tracing rays generated by different points of the object to an image plane and ii) summing the rays from the different points. The rays may be traced through a lens array.

摘要： A sheeting and a method of forming a sheeting from a master tool are described where the sheeting has a composite image that floats above or below the sheeting. The method includes providing a first sheeting comprising a first array of microlenses and a photopolymerizable first material layer adjacent to the first array of microlenses. Another step is exposing the first sheeting to a radiation source to form a master tool comprising a plurality of polymerized first structured areas in the first material layer, wherein at least some of the first structured areas include a portion shape in common with at least some of the first structured areas and wherein each first structured area is associated with one of the first array of microlenses. Yet another step is replicating the plurality of first structured areas using a substance that conforms to the plurality of structured areas to form a second material layer having a plurality of replicated structured areas.
