  • Patent number: 10969343
    Abstract: A measuring method includes: illuminating a silicone-coated layer using a light source; and imaging light from the light source that is specularly reflected from the silicone-coated layer to form an image of a surface of the silicone-coated layer. The method further includes detecting pores and/or voids in a silicone coating of the silicone-coated layer from the image; determining a silicone coverage of the silicone-coated layer based on the detected pores and/or voids; and determining a release force of the silicone-coated layer based on the silicone coverage.

  • Publication number: 20210088500
    Abstract: A measurement apparatus of a moving paper web, includes an optical radiation source that outputs optical radiation toward a scattering element of the measurement apparatus. The scattering element scatters the optical radiation, and a transmitting surface of the scattering element directs the optical radiation in a scattered manner toward the moving paper web. A distance between said transmitting surface of the scattering element and a surface of the paper web is known, and the transmitting surface and a detector of the apparatus are on opposite sides of the paper web. The detector receives at least a part of the optical radiation, which is side-scattered from the moving paper web. The detector determines a moisture value and a dry weight of the paper web on the basis of spectral information on the received optical radiation and the known distance.

  • Patent number: 10444143
    Abstract: Optical multi-channel measurement unit for a process measurement includes first ends for receiving optical radiation from the optical radiation source, and second ends for outputting the optical radiation for illuminating the at least one object. Optical detectors receive optical radiation from at least one measurement channel via at least one optical filter and convert an intensity of the optical radiation to an electrical signal. A movement mechanism causes, for filtering the wavelengths of the optical radiation propagating between detectors and the optical measurement channels through the optical filters, at least one of the following: movement inside at least one optical filter and movement between the filters and the detectors.

  • Patent number: 9574994
    Abstract: A detector receives optical radiation interacted with the measured sheet and is responsive to a predetermined optical absorption band of lignin, a predetermined optical absorption band of dry matter and two or more separate optical bands. The measuring unit measures a lignin dependent value on the basis of attenuation in the absorption band of lignin, and a dry matter dependent value on the basis of attenuation in the absorption band of the dry matter, and determines a general dependence of attenuation with respect to wavelength by measuring attenuations in the separate optical bands. The measuring unit forms a value representing a dry matter content on the basis of the lignin dependent value, the dry matter dependent value and the general dependence of attenuation.
