Summary:An apparatus and an associated method determine the fiber orientation of a moving fibrous web, in particular a paper, cardboard or cellulose web. An illumination device illuminates an area of the fibrous web and a camera records a digital image of the illuminated area of the fibrous web. The illumination device is configured to illuminate the fibrous web for a period of time of 1 μs or less and the camera is configured in such a way that the edge length of a pixel corresponds to no more than 20 μm, in particular no more than 10 μm.
