Abstract: Systems and methods for illuminating a platen are provided. A hybrid illumination system uses both diffusion and collimation to efficiently provide a flat, uniform illumination at a platen. One or more diffusers are disposed between the illumination source array and a collimating lens. An illumination system is provided which uses diffused light to illuminate a platen in a print scanner. The illumination system has an illumination source array and a light wedge. The light wedge reflects light internally which makes the illumination even more diffuse. Sources are divided into at least a center region and a perimeter region. The density of sources provided in the perimeter region is greater than in the center region to correct for natural light falloff in the illumination system. Intensity control can be performed individually or in groups.

Abstract: A system and method are provided for scanning all or part of a hand print for one or more hands positioned on a non-planar portion of a prism. The non-planar portion can be symmetrical about an axis of symmetry of the prism. Typically, a palm pocket, writer's palm, or the like, is hard to capture on a flat surface. In contrast, the non-planar portion of the prism according to embodiments of the present invention provides a form so that the palm pocket, writer's palm, or the like, can be captured. Hand and/or finger characteristic data can also be captured, for example hand geometry (e.g., finger lengths and spacing between fingers). The prism can also include a positioning device (e.g.

Abstract: This invention relates to an apparatus for optically comparing data stored in a holographic medium with data stored in a holographic database. The apparatus includes a beam emitter and a holographic database. The beam emitter emits a reference beam onto the holographic medium and projects a holographic image that corresponds to the data stored in the holographic medium. The holographic database is configured to receive the projected holographic image and to compare it with holographic image data contained in the holographic database. When a match is found or when all of the objects' holographic images on the database have been compared, the database emits a result signal.

Abstract: This invention relates to the use of holographic optical elements in the design and application of biometric scanning instruments used typically for capturing biometric information such as fingerprints and handprints. Applications of holographic optical elements include providing several novel operational features involving display, annunciation, and control of biometric fingerprint and handprint scanning instruments. The holographic elements may be used to create an active platen. The active platen may be illuminated to project graphical displays on the platen such as time stamps, instructions to users, or feedback on print quality.

Abstract: This invention relates to the use of holographic optical elements in the design and application of biometric scanning instruments used typically for capturing biometric information such as fingerprints and handprints. A live print scanning system for generating a high contrast print image is presented. The system includes a flatbed scanner with a scanning surface and an image sensor, a holographic platen placed on the scanning surface, and a reference beam source that provides a reference beam to the holographic platen. A high contrast print image of a biometric object that is placed on the holographic platen is obtained at the image sensor. A method for generating a high contrast print image is also presented.

Abstract: This invention relates to the use of holographic optical elements in the design and application of biometric scanning instruments used typically for capturing biometric information such as fingerprints and handprints. Holographic optical elements provide the opportunity for fingerprint scanning manufacturers to reduce product development cycle times, reduce product cost, size, and weight, and provide optical design flexibility not afforded by common glass and plastic optical elements. The present invention discusses various instrument embodiments employing holographic optical elements utilizing methods of holographic image reconstruction.

Abstract: This invention relates to the use of holographic optical elements in the design and application of biometric scanning instruments used typically for capturing biometric information such as fingerprints and handprints. A system and method for capturing print images from select areas of a platen are presented. The system includes a reference beam source that provides a reference beam, holographic material that receives the reference beam, a platen on a surface of the holographic material that receives a biometric object, and an image sensor. Variations in orientation of the reference beam cause differing areas of the platen to be mapped onto the image sensor, thereby obtaining both different image translations and magnifications of at least a portion of the biometric object.

Abstract: A directionally-oriented reflective device is optically coupled to a prism surface in a skin ridge pattern imaging system to reflect illumination light at relatively small angles, along an optical path to an imaging device, so that minimal light is lost from the optical system. Examples of such directionally-oriented reflective devices include, but are not limited to, echelon reflectors, faceted reflective surfaces, retroreflectors, aluminum paint, nacreous pigment, and slightly rough mirror surfaces.

Abstract: A surface pattern imaging device applicable to fingerprint and other surface imaging applications operates with an illumination source. In an embodiment, the illumination source is a narrow band green light, and an optical imaging path of the reader includes a green band pass filter and an infrared (IR) cutoff filter between the surface of interest and an image sensor. The filters prevent ambient light outside the green range from reaching the image sensor. In an exemplary embodiment useful in fingerprint imaging, ambient light wavelengths in the green range are absorbed and blocked naturally by the finger, and therefore cannot pass through the finger into the imaging path. Ambient light in other ranges, particularly including the red and infrared ranges which may pass through the finger, is attenuated by the band pass and IR cutoff filters.

Abstract: Devices and methods for applying heat to a platen of a biometric image capturing device are described that remove and prevent the formation of excess moisture on the platen. These devices and methods prevent undesirable interruptions of total internal reflection of a prism that result in biometric images having a halo effect. In embodiments of the invention, heater assemblies, such as electrically conductive transparent material or resistive heating elements, can be used to heat an area where a biometric object is placed to remove and prevent the formation of excess moisture on the platen. Cooling assemblies, such as electrically conductive transparent material or Peltier elements, can be used to decrease temperature of an area where a biometric object is placed to prevent overheating of the platen.

Abstract: A system and method for obtaining a biometric image such as a ten-print fingerprint impression is provided. The system and method can include a live scanner having a platen and a finger guide coupled to the platen. The finger guide can be used to guide positioning of up to four fingers at a time onto the platen, and can include a physical barrier for separation of fingers or thumbs. The finger guide and physical barrier allow a determination of whether a left or right hand is placed on the platen. Fingerprint images can be separated into individual fingerprint images that can be placed onto corresponding areas of a fingerprint card.

Abstract: A live print scanner includes a transparent tray platen apparatus and a scanning system. The transparent tray platen apparatus includes a base region attached to two rounded side regions. The base region of the tray platen assembly includes a convex portion. A hand is placed atop the base region adjacent to one of the two rounded side regions such that the hand's palm pocket is atop the convex portion. A sensor assembly within the rotary scanning system generates a complete image of a palm print pattern. Because of the side regions and the convex portion, the image generated includes an image of a print pattern on the palm pocket as well as on the side of the palm. A holographic element may be disposed in a light path between an illumination source and the sensor.
