    • The invention relates to an arrangement for imaging the topography of the surface of a moving web in illumination that is implemented with such incoherent radiation that has at least a first wavelength component and a second wavelength component, arranged to be received with wavelength-component-specific cameras at the end of a wavelength-component-specific branch of an optical path leading to each camera, which optical path has sequentially in the travel direction of said radiation after the source of radiation said point of the surface to be imaged, a wavelength-selective film for directing said first wavelength component to a first wavelength-specific camera by reflection from said film along a first wavelength-component-specific branch of the optical path and for directing said second wavelength component to a second wavelength-specific camera through said film along a second wavelength-component-specific branch of the optical path, in order to store each image taken by a camera on a storage medium along with the pulsing of the lighting. The invention also relates to a method and a system as well as their use in a printing machine and/or a paper machine for monitoring the composition and/or structure of a paper web.
    • 本发明涉及一种用于对照明中的移动幅材的表面的形貌进行成像的装置,所述布置采用具有至少第一波长分量和第二波长分量的这种非相干辐射来实现,所述第一波长分量和第二波长分量布置成以波长分量特定 在通向每个照相机的光路的波长分量特定分支的末端处的相机,该光路在辐射源之后在所述辐射源的所述辐射的行进方向上依次具有待成像的表面的点, 选择性膜,用于通过从光路的第一波长分量特定分支的所述胶片的反射将所述第一波长分量引导到第一波长特定相机,并且用于通过所述胶片将所述第二波长分量引导到第二波长特定相机 沿着光路的第二波长分量特定分支,以便存储由相机拍摄的每个图像 存储介质以及照明的脉冲。 本发明还涉及一种方法和系统,以及它们在印刷机和/或造纸机中用于监测纸幅的组成和/或结构的用途。
