    Abstract: A measuring device comprises a first optical sensor row (200) and a second optical sensor row (202) between which a planar object (204) to be measured is placed. The direction of the first sensor row (200) and the direction of the second sensor row (202) differ from one another. Each sensor (208) of the first sensor row (200) forms data representing a distance between the object (204) to be measured and the sensor (208). Each sensor (210) of the second sensor row (202) forms data representing a distance between the object (204) to be measured and the sensor (210) in order to determine at least one property of the object (204) to be measured on the basis of said data.

    Abstract: Optical radiation sources (206, 208, 300) functioning on different optical bands radiate on different optical bands and focus optical radiation on a region (210) in a web (10) surface as pulses in such a manner that illumination areas of the pulses overlap on the plane of the web (10). At most one optical radiation band is focused on the web (10) from the direction of the normal. The spatial intensity distribution of at least one optical band differs from the uniform distribution and the intensity distributions of at least two different optical bands differ from one another in a predetermined manner. A camera (202) forms still images of the web (10) surface region (210) on each optical radiation band. An image-processing unit (204) determines the surface topography of the web (10) on the basis of the images. In addition, a controller (126) may control the paper manufacturing process on the basis of the determined surface topography.
