摘要： A method and apparatus for applying gradient edge detection to detect features in a biometric, such as a fingerprint, based on data representing an image of at least a portion of the biometric. The image is modeled as a function of the features. Data representing an image of the biometric is acquired, and features of the biometric are modeled for at least two resolutions. The method and apparatus improves analysis of both high-resolution images of biometrics of friction ridge containing skin that include resolved pores and lower resolution images of biometrics without resolved pores.

摘要： A method and an apparatus for recording at least two multiplexed holograms. The object beam and the reference beam generated by a coherent light source. Either an object beam or a reference beam is reflected from at least one portion of an aspherical reflecting surface causing the object beam and the reference beam to intersect and form an interference pattern at a plane defined by the intersection of the object and reference beams at a selected storage location in a recording media. At least one of a portion of the reference beam impinging on a recording media at the selected storage location and a portion of the object beam impinging on the recording media at the selected storage location is rotated through a selected azimuthal angle about an axis that lies in the plane formed by optical axes of the portions of the object beam and the reference beam impinging on the recording media, wherein the axis passes through a plane defined by the intersection of the object beam and the reference beam in the recording media, and wherein an angle between optical paths of the portions of the object beam and the reference beam impinging on the recording media is preserved.

A method of making the siloxane includes charging (HMe2SiO1/2)a(MeHSiO2/2)b(HSiO3/2)c(SiO4/2)d, a platinum catalyst, and an alkene of the formula CR′2═CR′—Y—Z or CR′2═CR′—Z into a reactor to form the siloxane. The siloxane is useful as a component in holographic storage media for photopolymer-based holographic data storage applications. The siloxane exhibits excellent compatibility when mixed with a polymerizable component before the polymerizable component is cured. Furthermore, the siloxane exhibits excellent diffusion from polymers of the polymerizable component after partial and complete curing. The siloxane also has a high refractive index while maintaining the excellent compatibility and diffusion properties when mixed with polymerizable component.

摘要： A method of recording a plurality of holographic images in a holographic media, comprising recording a sequence of multiplexed holograms in a selected storage location in the holographic recording media, each hologram having a respective interbeam angle. The interbeam angle increases for each subsequently recorded hologram to compensate for a variable shrinkage of the holographic media during recording. The multiplexed holograms recorded at the selected storage location are partially or fully overlapped. During reading the recorded holograms, a reference beam is directed at a selected storage location in the holographic recording media at a sequence of incidence angles, each incidence angle being adjusted by a respective adjustment angle. The adjustment angles can be substantially equal.

摘要： Holographic data storage systems are fixed after exposure during which data in the form of holograms are stored at locations in the medium (4). Sufficient fixing energy in the form of light or other electromagnetic and thermal radiation is applied to the media (4) either by flooding the media, or to specific locations where the medium has been written. The energy is sufficient to expose the recorded medium (4) to prevent recording in the unused dynamic range thereof. Such recording can be a spurious recording made during readout or from spurious sources of light incident on the media. In one embodiment, the reference beam (108) produced in the course of holographic recording is redirected to locations on the media (4) which have already been recorded. The redirected beam post exposes the media to fix these locations against spurious recording. The integrity of the holographic data storage systems and the robustness thereof is improved by fixing methods and apparatus incorporating the invention.
