Abstract: An inspection arrangement for fluorescence-based inspection of a product containing at least one fluorophore having an excitation spectrum and an emission spectrum, the inspection arrangement including a radiation source for generating a first electromagnetic radiation in a first wavelength range containing an excitation spectrum and a second electromagnetic radiation in a second wavelength range containing the emission spectrum, an imaging device for generating images of an inspection area in which the product can be arranged, and an image data processing device for image processing of the images. The inspection arrangement captures with the imaging device at least one fluorescence image of the inspection area irradiated with the first electromagnetic radiation and at least one reference image of the inspection area irradiated with the second electromagnetic radiation.

Abstract: A device for generating a photometric stereo image and a color image of an object which is moved at a predetermined relative speed relative to the device. The device includes a lighting area and a lighting arrangement which is oriented to the lighting area. The lighting arrangement cyclically emits a lighting sequence in the lighting area. The lighting sequence has at least four lighting pulses each of which have a wavelength range and a lighting direction. At least three of the at least four lighting pulses have a different wavelength range, and at least two of the at least four lighting pulses have a different lighting direction and a same wavelength range.

Abstract: An arrangement for an inspection of plate-shaped objects moving relative to a camera device in a direction of motion through at least two observation areas. The arrangement includes the camera device which includes one single camera which comprises a matrix sensor, and an image processor. In a first detection state, a first observation area running diagonally opposite to the direction of motion is represented on a first image area of the camera device and is recorded as a strip-shaped image. In a second detection state, a second observation area is represented on a second image area of the camera device and is recorded as a strip-shaped image. The image processor merges the strip-shaped images recorded in the first detection state and in the second detection state to form two-dimensional images. All image areas are located on the matrix sensor.

Abstract: A Multisensor array optically inspects and sorts bulk materials into different fractions, in which the bulk material stream is detected from a short distance compared to the width of the bulk material stream with at least two identical camera and lighting modules arranged adjacent to each other. The width of the image of the cameras is smaller than the width of the bulk material stream. The image sensors and lighting devices are limited to the range of the wavelengths of 380 nm to 1,000 nm covered by CMOS and/or CCD image sensors. Each camera is connected by a mechanical bracket and is equipped with at least one and preferably with a set of linearly lighting semiconductor light sources, which emit in a narrow band and are pulsed synchronously with the line frequency of the camera. The linearly lighting light sources can be replaced by a changing mechanism of the bracket, which mechanism is connected to the camera, to other light sources, especially ones having different system parameters.

Abstract: A method is disclosed that relates to maintaining or improving the end quality of the visual color imprint of multiple-colored patterned surfaces. These surfaces cannot be measured using the decorations that are manufactured by printing processes, the so-called primary decoration, because subsequent processes change the color imprint further resulting in the so-called secondary color imprint. According to the invention, prediction rules are determined based on samples from the primary and secondary decorations during a learning phase to establish from n-channel images of samples of the primary decoration color imprint characteristics and convert those to such characteristics for the secondary decoration; and/or to establish from n-channel images of samples of the primary decoration images of the secondary decoration and to calculate color imprint characteristics.

Abstract: A method and an arrangement for testing the quality of multicolor patterned surfaces with an n-channel imaging sensor such as a color camera or an imaging spectrometer. The method determines from the captured images the deviations of the color/spectral statistics and of the image sharpness with respect to references and, before an assessment, converts at least one of the deviations or threshold values using a transformation which emulates the genetically and/or culturally specific perception of the targeted customer groups. The method further allows a quality produced to be associated with a genetically and/or culturally specific group of customers who accept this quality in terms of their perception of multicolor patterned surfaces.
