  • Publication number: 20030072002
    Abstract: The present invention relates to a densitometry device that can perform suitable densitometry with minimum required light amounts and can achieve space savings. An angle &thgr; between a reference optical axis of a light source, which is an LED chip, and an optical axis, according to a photoelectric conversion element, of a density measurement optical system is set to, for example, 52°. Light-emitting chips, which emit each of red, green and blue light, are provided inside a cannon shell-shaped light-emitting portion. These light-emitting chips are arranged in a straight line along a direction of conveyance of a color patch chart. Consequently, inclination angles of the light-emitting chips with respect to a measurement axis of the density measurement optical system will always change consistently with each other, and no difference between the inclination angles of the different colors will occur.

  • Publication number: 20030072003
    Abstract: A system and a method for recording interference fringes in a photosensitive medium. Two light beams are guided along different light paths to impinge on a photosensitive medium, where they interfere to produce the interference fringes. One of the beam is reflected along its path on a delay mirror forming a fixed angle &phgr; with respect to the plane of the photosensitive medium. Both the photosensitive medium and delay mirror are translated with respect to the light paths of the two beams, thereby recording the interference fringes all along the medium. The angle &phgr; is chosen so that the interference pattern is fixed relative to the photosensitive medium along its length.

  • Publication number: 20030072005
    Abstract: A high accurate SOI optical waveguide Michelson interferometer sensor for temperature monitoring has designed and analyzed in this invention. According to the numerical analysis of power reflective spectra of waveguide Michelson interferometers, the temperature sensing of waveguide SOI Michelson interferometer sensor can improve at least 20 times than fiber Bragg grating temperature sensor. Moreover, the SOI Waveguide interferometer sensor we designed presents high sensitivity than pure single waveguide Bragg grating sensor and fiber Bragg grating sensor by adjusting the length of the two interferometric arms. The full wavelength half maximum (FWHM) of our designed SOI optical waveguide Michelson interferometer can be narrowed much smaller than fiber Bragg grating and waveguide Bragg grating sensors for sensitivity improvement. The invention of this optical SOI waveguid sensing devices shows promising results for developing integrated OEIC sensors in the future.

    Abstract: The invention is directed to the detection and imaging of the internal geometry of the eye, particularly of the important components for imaging in the eye such as the cornea, lens, vitreous body and retinal surface, by multichannel short coherence interferometry. A method and arrangement for obtaining topograms and tomograms of the eye structure by many simultaneously recorded interferometric depth scans through transversely adjacent points in the pupil using spatially coherent or spatially partially coherent light sources. The depth scan is carried out by changing the optical length of the interferometer measurement arm by means of a retroreflector. By continuously displacing the retroreflector, the z-position of the light-reemitting point in the eye can be determined by means of the occurring interference. It is possible to record depth scans simultaneously through the use of spatially coherent or spatially partially coherent light beams comprising a plurality of partial beams.

  • Publication number: 20030072010
    Abstract: A wavelength detector includes an optical structure receiving an input beam, the optical structure outputting at least two wavelength dependent two-beam interference signals. Each wavelength dependent two-beam interference signal has a different phase offset. A detector receives the at least two wavelength dependent two-beam interference signals and outputs an electrical signal representative of each wavelength dependent two-beam interference. A processor receives the at least two electrical signals from the detector and generates a composite control signal. The two-beam interference signals may be created by reflecting light off the two surfaces of the optical structure. The different phase offsets may be created by providing a stepped pattern on one of the surfaces of the optical structure. Phase shifting interferometry techniques may be used to determine the wavelength from the periodic signals.

The digital image is processed and imprinted frame by frame by adding black metamers to the fundamental metamer of selected pixels in a frame. The black metamers imprint the identifier into the digital image without changing the way in which the image is perceived visually. To verify that a copy of a digital image imprinted with an identifier has been made, the suspected copy of the digital image is stripped of all fundamental metamers to reveal only its black metamers. The presence of an identifier within the black metamers is evidence that the suspected copy is in fact a copy of a digital image.

  • Publication number: 20030072044
    Abstract: An image determination apparatus, an image reading apparatus, and an image determining method include a device for cutting a color/monochrome region based on a color saturation value obtained by a predetermined derivation method based on image data, and a device for detecting image errors located in large boundaries of brightness variations including color distortions based on correlations between color saturation and color. When errors are included in the image data acquired by, for example, a color image scanner due to primary color errors at random locations (in particular, color bleeding that occurs as a color distortion in monochrome achromatic color areas), it is possible to extract characteristics from the image data and detect locations in images where color distortions and color bleeding occur without using especially complicated and special compositions to detect where these errors occurred.
