  • Agricultural sampling apparatus and system
    Patent number: 11320369
    Abstract: In one embodiment, an agricultural sampling apparatus is provided. The apparatus comprising: a wave emitter; a wave transmitter configured to direct the waves from the wave emitter as a plurality of linewise waves to irradiate surface points of the agricultural sample; a dispersive element configured to receive waves arriving from the sample and deflect the arriving waves in at least two directions depending upon the wavelength of an arriving wave; and a detector configured with a plurality of detection elements disposed in at least two dimensions, the detector configured to convert the waves arriving from the dispersive element to a signal.

  • Apparatus for illuminating the surface of a material
    Patent number: 10473523
    Abstract: An apparatus for illuminating the surface of a material, comprising an illuminating device for illuminating the surface of the material with a calibrating light, a recording device for recording a measuring light, emitted by the surface of the material in response to the calibrating light, and a processor device for recording the spectral characteristic of the measuring light that characterizes a diffuse spectral reflectance of the surface of the material, wherein the illuminating device is configured to generate an illuminating light for illuminating the surface of the material that has a spectral characteristic that corresponds to the spectral characteristic of the measuring light.
