Abstract: A surface pattern (10) has two surface portions (11; 12) with microscopically fine, light-diffracting relief structures. The relief structures are in the form of grating structures GS1 or GS2, respectively, which are composed of at least two superimposed gratings G1 and G2, G3 and G4, respectively. The light-diffracting properties of the gratings G1 to G4 are so selected in accordance with various criteria that novel optical effects which cannot be holographically copied can be achieved with the grating structures GS1 and GS2. Such surface patterns are suitable as optical security elements for documents or articles of all kinds as well as packaging foils.

Abstract: A light control material generally comprising a transparent substrate (113) for carrying a print or photographic image and a plurality of focusing elements (114) which provide a field of view over which the brightness of the print or photographic image is enhanced. The field of view is controlled by the geometry of the focusing elements (142) including radius, width, and degree of symmetry. By providing a field of view (112) over which the brightness of the image is enhanced, the image may be viewed at angles which avoid the angles of specular reflection, which are usually seen as unwanted glare. Furthermore, selected portions of an image may be brightness enhanced more than others or selected portions may be brightness enhanced while others are not.

Abstract: The present invention is directed to a diffractive display suitable for presenting graphic and the like displays. Broadly, the novel display is realized from a diffraction pattern (132) carried by (e.g. embossed) a film or element (138) connected to an energy source which is energizable for movement of the film (138). Movement of the patterned film (138) generates a display using the diffracted light from the embossed pattern (132). Electroactive films are known in the art, including, for example, piezoelectric films, electrostrictive films, electromotive films, and electrostatic films. Magnetoactive films also are known in the art. Any of these films (138) can carry the diffraction pattern (132) and be energized for movement to generate from the resulting diffracted light.

Abstract: A method and apparatus for splitting, scanning and receiving a beam of light is disclosed. Binary optic array components are used to split, in an angular manner, an input beam into multiple beams, travelling in different directions. Miniaturized array element BOCs arranged in ''n'' different groups are used, wherein n is dependent upon the number of split beams needed or desired. An offset is introduced between the optical axis of each of the corresponding pair of miniaturized BOCs. By varying the offset over time, the resultant beam(s) can be scanned in one, two or three dimensions. Piezo-electric drivers controlled by a processor may be used to move the array in order to vary the offset. The device may also include a collection area to collect the returned scanned beams by using an array of optic components integrated with the scanner. The collected beams are then focused onto detectors.

Abstract: An intraocular lens including a refractive/diffractive lens having an anterior surface and a posterior surface and a generally anterior posterior optical axis. At least one of the surfaces has a diffractive lens profile that is binary in phase, and produces three useful focal points. The diffractive lens profile is designed to provide three foci each containing 28.8 % of the incident light, with the residual 14 % of the light going into other foci. Additionally, some of the out-of-focus light of this design contributes positively to the image, and the resultant maximum image contrast is above 28.8 %. This design adds clear mid-range vision, at the expense of a slight decrease in near and far vision, and the added mid-range vision makes the device less sensitive to longitudinal placement in the eye.

Abstract: A lens (10) composed of a single material and having at least one refractive surface (14) on one face and a kinoform (20) on the other face (16). The pure refraction between the surfaces varies dimensionally and in refractive index in response to temperature changes and thereby changes characteristics, such as the back focal length, of the lens while the kinoform varies differently in response to the same temperature changes. The kinoform power is sufficient to vary the temperature induced characteristic changes of the lens in an opposing sense at a given wavelength and in an amount sufficient to athermalize the optical device. In one embodiment the kinoform power compensates for the combined temperature-induced effects upon the refractive portion and any mount that supports the lens.

Abstract: An optical fibre (2) is fixed between a clamp (6) and a piezo-electric translation stage (10). An argon ion laser (12) emitting at 514.5 nm is used to write Bragg gratings in the fibre (2). A different longitudinal stress is applied to the fibre (2) before optically writing each Bragg grating. The fibre (2) when unstressed will have a Bragg grating of different peak reflectivity corresponding to the number of different applied stresses.

Abstract: A transmission grating (5) is used to reduce chromatic aberration in an optical system, wherein the system's chromatic dispersion is offset and substantially canceled by the grating's diffraction-induced dispersion. The grating (5) comprises a Fresnel-type pattern of microscopic facets (4) molded directly into one of the system's refractive optical surface (3). The facets (4) would typically have a profile height of around 4.10-5 inch and a profile width of at least 10-3 inch. In its primary intended application, the invention would function to improve the optical performance of a Fresnel lens used to concentrate direct sunlight into a piped daylight illumination system. For this application, about a ten-fold reduction in chromatic dispersion would be attained with only about a 2 % loss in optical efficiency.
