    Abstract: The present invention relates to a device and a method for determining the quality of surfaces. An illuminating means of a first optical means radiates light at a predetermined angle onto the measurement surface. A second optical means is likewise aligned at a predetermined angle to the measurement surface and a photosensor receives the light reflected from said measurement surface and converts same into an electrical measurement signal which is characteristic of the reflected light. A control and evaluation means comprising a processor and memory means controls the measurement sequence and evaluates the measurement results, which are emitted via an output means. The illuminating means comprises at least one light-emitting diode. The light emitted by said illuminating means is configured such that its spectral characteristic comprises at least blue, green and red spectral components in the visible range of the spectrum. A filter means is provided in the path of radiation between the light source and the photosensor. The evaluating means evaluates the reflected light and derives therefrom a parameter which characterizes the surface.

    Abstract: An object recognition system comprises a sensing apparatus for collecting light reflected from objects presented at a point-of-sale machine. The sensing apparatus includes a mechanism, such as a holographic disk or diffraction grating, for separating the color components of the light reflected from the object and directing, the color components onto an optical detector such as a two-dimensional imaging array, or a one-dimensional imaging array or single photo-sensitive optical cell used in conjunction with a rotating mirror. A pattern recognizer compares the spectral response, including the locations, amplitudes and widths of energy peaks of the different color components, against premeasured characteristics of known objects in order to classify the object. The weight of the object can be measured with a scale, and the density of the object calculated, with the weight and density being used by the pattern recognizer to further classify the object. In one embodiment, a plurality of narrowband illumination sources are operated in time-sequential manner, each illuminating with a different wavelength band of light, in order to allow separate color measurements. The object recognition system may be integrated in a single unit along with an optical code reader, and may share all or part of the same exit aperture therewith. The object recognition system may include thermal detection or a particle source and secondary emission detection device, either alone or in conjunction with other object recognition means.

    Abstract: An image sensing apparatus of the type employing resolving and sensing means is provided with sensing means of selected size and geometry to allow approximation of arbitrary filter response. The sensing means of selected size and geometry may be incorporated into compact, self contained image resolving and sensing apparatus having a transparent substrate for resolving an incident image by refraction, diffraction or other suitable mechanism. The sensing means may be located directly on a surface of the transparent substrate. Logic and select circuitry may be integrally and simultaneously formed with the sensing means. The size and geometry of the sensing means may enable approximation to color inhibition and other effects to allow approximation of the spectral response of the human eye.

    Abstract: A method of optically measuring chromatic densities of a sample. In the method, three stimulus values, X, Y and Z, of light reflected from the sample, are derived. A cyan density, a magenta density and a yellow density are determined for the sample, using the X, Y and Z stimulus values, and in addition, three stimulus values, Xo, Yo and Zo of a standard color, such as white. With this method, a color image of an original picture may be accurately reproduced with a high fidelity.

    Abstract: In a color measuring instrument, an integrating sphere is used to illuminate the sample and fiber optics are used to carry light diffusely reflected from the sample and from an interior wall of the sphere to a spectrometer. The transmitting ends of the fiber optic bundles are fixed in the housing of the spectrometer as entrance slits for the spectrometer, which includes a fixed grating and one or two arrays of photodetectors to detect the spectra dispersed by the grating from light received from the two transmitting ends.
