Abstract: Percentage concentrations of constituents of a sample of cereal grain or other agricultural product in a flowing stream are determined while harvesting or processing using a short wave near infrared analyzer. The analyzer irradiates the sample, picks up diffuse reflectance of individual wavelengths from the sample and spatially separates the diffuse reflectance into a response at individual wavelengths. The result is to simultaneously detect the intensities of the individual wavelengths in parallel from the same portion of the product being analyzed. Percentage constituents of the composite substance may then be compared with known percentage constituents to determine the constituents in the sample product. The inventive wavelength analyzer is suitable for attaching to the agricultural combine to perform real time measurements in the field.

Abstract: Method and apparatus (70) for sensing the color of articles (82) and for classification thereof, wherein a first pair of wavelengths is selected on a plurality of light reflection curves (12-22) in terms of a reflected light wavelengths spectrum. An article (82) to be inspected is illuminated with light (98) comprising the first pair of wavelengths and light reflected (100) therefrom is measured to detect light reflection values corresponding to this first pair of wavelengths. A primary signal is produced, which represents either a difference between or a ratio of the detected light reflection values, this signal being indicative of the color of the inspected article (82). At least one secondary wavelength is selected on the reflected light wavelength spectrum, and the inspected article is illuminated with light comprising this secondary wavelength and light reflected therefrom is measured to produce a secondary signal which is further indicative of the color of the inspected article. A computer (78) provides a classification frame (42) comprising a first pattern consisting of first and second crossing sets of lines (44, 46) respectively defined by mathematical analysis, this classification frame defining a plurality of color classes (Cij). The computer (78) classifies the inspected article in one of the plurality of color classes defined by the frame (42), whenever the primary and secondary signals comply with a specific condition. The computer (78) rejects the inspected article (82) whenever the primary and secondary signals do not comply with this specific condition.

Abstract: An optical characteristic measuring apparatus and an optical characteristic measuring method of the invention are an optical characteristic measuring apparatus and method for obtaining a predetermined optical characteristic such as a color value or a total spectral radiation factor of a measurement object. A spectral intensity distribution of predetermined ambient light entering through a measurement opening is measured and stored prior to measurement of the optical characteristic. In measuring the optical characteristic, an optical characteristic in a condition that actually measured ambient light is used as an observation light source is obtained, with use of the stored spectral intensity distribution of ambient light.

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.
