  • Patent number: 10288979
    Abstract: The present disclosure describes the design and fabrication of a Terahertz (THz) beam steering device and a multifunctional patternless flat lens using electro-optic tunable fishnet materials (TFMM) to create a portable THz imaging system. The THz beam steering device and multifunctional patternless flat lens utilize a tunable resonant frequency of TFMM (with a negative refraction index) to achieve a maximum beam steering angle (field of view) and beam modulation. The portable THz scanning system is made by combining the TFMM beam steering device with a pair of continuous wave (CW) photomixer modules powered by two tunable CW lasers with built-in optical isolators, a fiber-optic beam combination and a multifunctional flat lens.

  • Patent number: 9597688
    Abstract: The invention relates to polymer substrates which are provided with fluorescence features and in which photochemical fluorescence features, i.e. fluorescent structures, are produced by UV irradiation. Thus, fluorophores can be produced in polymer substrates with a low inherent fluorescence by means of suitable UV radiation, which fluorophores display a marked and detectable emission upon being excited with light of a suitable wavelength. If such an irradiation is implemented in a structured manner, emission patterns can be produced in this way in polymer substrates, which emission patterns can be applied for example as recovery grids in fluorescence microscopy. A further application field relates to product authentication which is made possible by the polymer substrates according to the invention provided with fluorescence features.

    Abstract: Methods and apparatus for article authentication include an exciting radiation generator that exposes an area of the article to exciting radiation, and at least two radiation detectors that detect emitted radiation from the area in a first band and in a second band that does not overlap the first band. The first band corresponds with a first emission sub-band of an emitting ion, and the second band corresponds with a second emission sub-band of the same emitting ion. A processing system calculates a comparison value that represents a mathematical relationship (e.g., a ratio) between a first intensity of the emitted radiation in the first band with a second intensity of the emitted radiation in the second band, and determines whether the comparison value compares favorably with an authentication parameter. When the comparison value compares favorably with the authentication parameter, the article is identified as being authentic.

    Abstract: In a method for introducing an authentication print characteristic in a visible image printed on paper, a part of the image is printed with an ink having first and second component dyes. The first component is less fast than the second component in response to an applied activator. The first component is normally masked by the second component but applying an activator stimulates a bleed of the first component beyond the area of the image part to create a predetermined unmasked area of the fluorescent component. The invention extends to paper on which the authentication print characteristic has been printed and to a method of detecting a forged image by analyzing paper to detect such an image bleed.

    Abstract: At least two luminescent materials are intermingled within a security feature. The materials are selected from among a larger set of luminescent materials each having a different individual exponential decay characteristic (decay constant and initial amplitude response to the degree of excitation) for photo-luminescent emission from the respective material following excitation. The ratio of the decay constants for any two materials is greater than or equal to about 1.5. The selected materials are mixed in one of a plurality of predetermined ratios. The combined emissions from the intermingled materials appear, to an unsophisticated measuring device, to have a single exponential decay constant. Based on measurements for the decay of the combined emissions following excitation, estimates of the individual decay constants and associated initial emission amplitudes allow decoding of the particular combination of materials and/or their ratios to validate the security feature, authenticating the article.

    Abstract: In embodiments, a pen digitizer includes a light source that generates light. The pen digitizer also includes light guides, such as fiber optics, configured coaxial within the pen digitizer to transfer the light from the light source and focus the light around an imaging tip of the pen digitizer. A photo array optically-images reflected light from encoded bits in an encoded micro pattern, and a lens focuses the reflected light onto the photo array.

  • Publication number: 20120074305
    Abstract: Presented is a system and method for verifying the authenticity of a part using non-destructive backscattered X-rays. The method uses an identification tag embedded in the part that when illuminated by X-rays returns backscattered radiation that is detected and used to authenticate the part. The system comprises a source of low energy X-rays that irradiate a part, a detector for detecting backscattered radiation returned from the part, and a means for determining the presence of an authentication tag in the part. In embodiments, the system and method use a tag made of a material that returns a high amount of backscattered radiation thereby providing a high level of contrast in comparison with the part. In embodiments, the placement of the tag in the part, the geometry of the tag, and coding in the tag are used to authenticate the part.

  • Patent number: 7960688
    Abstract: Disclosed are photoluminescent markings that contain a photoluminescent layer and one or more functional overlayers wherein the photoluminescent marking has an emission signature that lies partly or fully in the infrared region of the electromagnetic spectrum. One functional overlayer conceals the photoluminescent layer and blends into the background or blends with marks that are normally present, without significantly reducing the luminescent intensity of the photoluminescent layer. Another functional overlayer provides photolytic stability to the underlying photoluminescent layer. Also disclosed are functional overlayers that enhance the daytime observability of the infrared emissions. A further functional overlayer prevents the observability of a printed message with the naked eye. A combination of functional overlayers each providing a different function is also included.
