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.

A method includes scanning a radiation beam with respect to a multi-photon curable photoreactive composition. The radiation beam includes a power sufficient to at least partially cure a volume of the multiphoton curable photoreactive composition. The method further includes modifying a characteristic of the radiation beam as the radiation beam is scanned.

An exposure system includes a light source emitting a beam along an optical axis that is capable of inducing a multi-photon reaction in a resin. The exposure system further includes a resin undergoing multiphoton reaction, as well as an automated system including a monitor that measures at least one property of the beam selected from power, pulse length, shape, divergence, or position in a plane normal to the optical axis. The monitor generates at least one signal indicative of the property of the beam, and a sub-system adjusts the beam in response to the signal from the monitor.

The present invention provides a method for the formation of an organic coating on a substrate. The method includes: providing a substrate in a vacuum; providing at least one vaporized organic material comprising at least one component from at least one source, wherein the vaporized organic material is capable of condensing in a vacuum of less than about 130 Pa; providing a plasma from at least one source other than the source of the vaporized organic material; directing the vaporized organic material and the plasma toward the substrate; and causing the vaporized organic material to condense and polymerize on the substrate in the presence of the plasma to form an organic coating.

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.
