    摘要: A method for determining optical properties of a sample material includes: determining a first intensity of light in a first polarization state that was reflected by the sample material; determining a second intensity of the light in a second polarization state that was reflected by the sample material; forming the ratio between the first intensity and the second intensity, or vice versa. Further, an apparatus for determining optical properties of a sample material, comprising at least one detector device for determining a first intensity of light in a first polarization state that was reflected by the sample material and for determining a second intensity of the light in a second polarization state that was reflected by the sample material and at least one computing unit for forming the ratio of the first intensity and the second intensity, or vice versa.

    摘要: The invention relates to a method and to a device for determining a material property, in particular the aging state or the aging resistance, of a bitumen material, comprising the steps: applying a substantially monochromatic first excitation radiation of a first excitation wavelength to the bitumen material; measuring the intensity of a first fluorescence radiation, excited by the first excitation radiation, at a measurement wavelength; applying a substantially monochromatic second excitation radiation of a first excitation wavelength to the bitumen material; measuring the intensity of a second fluorescence radiation, excited by the second excitation radiation, at the measurement wavelength; determining a first key figure for the material property of the bitumen material from the ratio between the intensity of the second fluorescence radiation to the intensity of the first fluorescence radiation.

    摘要: A floating platform is provided including the following: a covering element; at least three buoyant bodies, which are separated from each other, are fixedly mounted to the lower face of the covering element, are open toward the bottom, and are made of a gas-tight, pressure- and corrosion-resistant flexible material. The buoyant bodies enclose a closed hollow space when coming into contact with a liquid surface. At least one compressed-air generating device is also provided for generating an overpressure in the individual hollow spaces.
