    Abstract: A hyperspectral imaging system and method are presented for use in reconstruction of spectral data of an object. The system comprises: a pixel matrix of a detector; a tunable dispersive unit in front of the pixel matrix; and a control system. The control system comprises: a controller for tuning the dispersive unit during n image acquisition sessions to provide n different partially overlapping spectral transmission profiles of the dispersive unit; and a control unit which is in data communication with the detector and is configured and operable for processing n image data pieces generated by the pixel matrix in said n image acquisition sessions respectively, each being indicative of a spectral image detected by the pixel matrix and corresponding to the different spectral transmission profile of the dispersive unit, and determining the reconstructed spectral data of the object.

    Abstract: A spectroscopic characteristics acquisition unit includes a light emitting unit to illuminate a measurement target; a lens array including lenses to receive reflected light reflected from the measurement target; a light blocking member having a pinhole array including openings; a focusing unit to focus light coming from the pinhole array; a diffraction unit to diffract the light to different directions depending on wavelength of light received by the focusing unit; and a light receiving unit to receive the reflected light diffracted by the diffraction unit. The light receiving unit includes a spectroscopic sensor array having spectroscopy sensors including pixels. Each of the lenses constituting the lens array corresponds to one of the openings of the pinhole array. The numerical aperture NA of the lens in the arrangement direction in the lens array satisfies the formula NA>sin (θmax) with respect to the maximum angle of view θmax of the focusing unit.

    Abstract: Eine Abtastvorrichtung für die punktweise Ausmessung der Farbeigenschaften eines Messobjekts umfasst eine Auflagefläche für das Messobjekt, einen Farbmesskopf, eine Antriebseinrichtung zur Bewegung des Farbmesskopfs über die Auflagefläche in wenigstens einer Dimension derselben und zur Höhenverstellung des Farbmesskopfs in Richtung senkrecht zur Auflagefläche sowie eine die Antriebseinrichtung ansteuernde und mit dem Farbmesskopf zusammenarbeitende Mess- und Antriebssteuerung. Sie ist mit einer elektronischen Abstandsregelung ausgestattet, welche mittels der Antriebseinrichtung für jeden Messpunkt den Abstand des Farbmesskopfs über dem Messort in Richtung senkrecht zur Auflagefläche auf einen Soll-Messabstand einstellt. Die elektronische Abstandsregelung arbeitet mit vom Farbmesskopf erzeugten Messwerten und daraus berechneten Abstandswerten.
    Die Abtastvorrichtung ist aufgrund ihrer spezifischen Ausbildung für die berührungslose, hochpräzise Messung auch von kleinsten Messfeldern geeignet und erfordert für die Abstandsregelung keine separaten Messfühler.
