摘要： 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.

摘要： 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.

The hand is placed on the non-planar surface of the optical element. A measuring device can be rotated about a centerline axis of the optical element. During the rotation, a circular image of the full palm print (including thenar, hypothenar, interdigital, palm heel, “writers palm,” palm pocket, and fingertips) and/or full palm and finger prints, and/or hand characteristic information (e.g., hand geometry, spacing, etc.) can be captured by the measuring portion.

摘要： Biometric object image capturing systems and methods prevent undesirable interruptions of total internal reflection of a prism that result in improper biometric images. A thermal assembly comprising a plurality of thermal elements is placed adjacent to the image capturing device. The thermal elements upon supply of a current are capable of either heating or cooling the image capturing device or a platen of the image capturing device. If cooling of the biometric object receiving surface is required, the thermal elements can be controlled to decrease temperature of an area where a biometric object is placed, or an area adjacent to where the biometric object is placed. If heating of the biometric object receiving surface is required, the thermal elements can be controlled to increase temperature of an area where a biometric object is placed, or an area adjacent to where the biometric object is placed, to remove and prevent accumulation of moisture.

摘要： 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., a hand-locating feature) than can be used to position a hand based on a point between a thumb and an index finger, between any other two fingers, a full hand on one side of the alignment device, both hands with each hand on either side of the alignment device, or to capture writer's palm and/or writer's palm and fingertip images.

摘要： 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.

摘要： 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. An illumination source array has a plurality of sources that emit blue/green light. In one preferred example, the blue/green light is equal to or approximately equal to 510 nm. 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 preformed individually or in groups.

摘要： 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, an electrically conductive transparent material is used to apply heat to the platen. In other embodiments, resistive heating elements attached to non-optical areas of the platen (e.g., the ends) are used to apply heat to the platen. Heater assemblies according to the invention can be used to heat an area where a biometric object is placed, or an area adjacent to where the biometric object is placed, to remove and prevent the formation of excess moisture on the platen.

摘要： 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.
