  • Method of and apparatus for obtaining high dynamic range spectrally, spatially and angularly resolved radiation data
    Patent number: 8599371
    Abstract: A method of obtaining high dynamic range, spectrally, spatially and angularly resolved radiance of a sample surface of a sample by an electromagnetic irradiator irradiating electromagnetic radiation of controlled spectral distribution onto the sample surface and, using an electromagnetic sensitive sensor to register the reflected spectral distribution. The spectral distribution of the intensity of the electromagnetic field is modeled to have been reflected by a plurality of spatially well defined part-surfaces of the sample surface.

  • METHOD OF AND APPARATUS FOR OBTAINING HIGH DYNAMIC RANGE SPECTRALLY, SPATIALLY AND ANGULARLY RESOLVED RADIATION DATA
    Publication number: 20110102784
    Abstract: A method of obtaining high dynamic range, spectrally, spatially and angularly resolved radiance of a sample surface of a sample, such as a paper sheet, accomplished by an electromagnetic irradiator irradiating electromagnetic radiation of controlled spectral distribution onto a sample surface of a sample and, using an electromagnetic sensitive sensor to register the reflected spectral distribution. The spectral distribution of the intensity of the electromagnetic field is modeled to have been reflected by a plurality of spatially well defined part-surfaces of the sample surface of the sample.

  • Determination of gloss quality
    Patent number: 6147750
    Abstract: A method and apparatus for obtaining a basis on which the gloss quality of a sample surface of a sample, such as a paper sheet, can be determined by illuminating the sample surface and registering the intensity of the reflected light.
