    Abstract: A spectral colorimetric apparatus includes a housing which includes a side wall. An outer surface of the side wall is an adjustment surface capable of adjusting a position of a light receiving member by moving in a state in which the light receiving member abuts on the adjustment surface. The light receiving member is supported by the side wall of the housing in a state in which the light receiving member abuts on the adjustment surface and receives a light beam that is dispersed by a concave surface reflection type diffraction element and passes through an opening portion. The adjustment surface is parallel to a tangential line at a part of a Rowland circle of the concave surface reflection type diffraction element, through which a light beam received by the light receiving member passes.

    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.

    Abstract: Zur visuellen Darstellung einer in elektronischer Form in einem Rechner vorliegenden Bildinformation auf einer Projektionsfläche werden die im Rechner (R) gespeicherten, die Bildinformation in einem Farbraum repräsentierenden Bilddaten in Form eines Videodatenstroms einer elektronischen Projektionseinrichtung (B) zugeführt. Diese erzeugt daraus entsprechende optische Signale erzeugt und projiziert diese auf die Projektionsfläche (L). Die Projektionseinrichtung (B) wird in ein Color Management System mit einbezogen. Dazu wird ein die Transfercharakteristik mindestens der Projektionseinrichtung (B) selbst beschreibendes Ausgabeprofil erzeugt. Anhand dieses Ausgabeprofils werden dann die Bilddaten nach den Prinzipien des Color Managements in den gerätespezifischen Farbraum der Projektionseinrichtung transformiert. Zur Profilerstellung wird in Verbindung mit einer Profilerstellungssoftware ein Lichtmessgerät (M) verwendet, welches entweder das von der Projektionseinrichtung emittierte oder vorzugsweise das von der Projektsfläche remittierte Licht erfasst und die dabei erzeugten Messdaten in die Profilerstellungssoftware einspeist.

    Abstract: A hand-held produce data collector which captures wavelength information from a produce item. The produce data collector includes a light emitter for illuminating a produce item, collecting optics for collecting light reflected from the produce item and separating the reflected light into a plurality of wavelength portions of light, a photosensor for capturing wavelength information from the wavelength portions of light, control circuitry, and a hand-held housing containing the light emitter, the collecting optics, the photosensor, and the control circuitry. The control circuitry may store reference wavelength information and compare the captured wavelength information to the reference wavelength information to identify the produce item.

    Abstract: A produce recognition system which identifies a produce item by comparing its color and texture information along a spatial area with reference information. The system includes a produce shape data collector including a light source for illuminating a produce item with light, a spectrometer which produces an image having a wavelength dimension and a spatial dimension from light reflected from the produce item, an image capture device which captures discrete wavelengths within the reflected light along the spatial dimension of the image and which produces an electrical signal, and control circuitry for controlling the light source and the image capture device and for digitizing the electrical signal. The system further includes a computer which determines color and texture information along the spatial dimension in the electrical signal and compares the color and texture information with reference information to identify the produce item.
