  • 3D grating optical sensor comprising a diffusion plate for conducting chromatometry with color constancy performance
    Patent number: 6704108
    Abstract: A grating optical sensor includes: a lens imaging an object space; a diffractive hexagonal 3D grating optical modulator in the image plane of the lens to form at least one trichromatic RGB diffraction pattern; a photoelectric receiver arrangement arranged in the near field downstream of the modulator, having individual receivers configured to generate electric signals in accordance with centrosymmetrically trichromatic RGB diffraction orders of the diffraction pattern; an evaluation device for the electric signals generated by the individual receivers; and at least one light-diffusion plate arranged in either a pupillary plane of the lens or a papillary plane conjugate to the lens or both.

  • 3D GRATING OPTICAL SENSOR COMPRISING A DIFFUSION PLATE FOR CONDUCTING CHROMATOMETRY WITH COLOR CONSTANCY PERFORMANCE
    Publication number: 20030053062
    Abstract: The invention relates to a grating optical sensor comprised of a lens (1) that reproduces an object space, of a diffractive hexagonal 3D grating optical modulator (4) in the image plane (5) of the lens (1), of a photoelectric receiver device (8), which is arranged in the near field behind the modulator (4) in accordance with the centrosymmetrically trichromatic diffraction orders (R, G, B), and of an evaluation device for the electrical signals generated by the individual receivers (8). The invention is characterized in that at least one light diffusion glass (9) is arranged in the pupillary plane of the lens (1) or in a pupillary plane conjugate thereto. The inventive sensor is used for conducting chromatometries with a color constancy performance via a thermal radiation source (17), which modifies the grating constants of the 3D grating (4) for a new white standard value.

  • Process and device for high-definition measurement of intervals in the focused image produced by a lens-aperture diaphragm system
    Patent number: 5982483
    Abstract: The invention relates to a method and apparatus for determining spatial aor time intervals in the focused image or focused sequence of images of a lens-diaphragm system and/or of spatial, time-related object-parameters (10), spectral and/or local frequency-specific object parameters, in particular to control automatons and to monitor production sequences, focusing of the incident electromagnetic beams being implemented by the lens-diaphragm system (10), position-specific modulation of the direction of propagation, intensity, wavelength, polarization and/or of the time modulation frequency of the electromagnetic beams (11) being implemented by a 3D modulator (12) present behind the lens-diaphragm system (10) in or near the focal plane of the lens-diaphragm system (10), detection of the modulated electromagnetic beams being carried out by a detection system (13) located to the rear of the 3D modulator (12), and calculation of the spatial and/or time intervals (14) of the electromagnetic beams in the 3D modulato
