  • MEASUREMENT OF OBJECT TO BE MEASURED
    Publication number: 20150008346
    Abstract: A measuring device includes a first optical sensor row and a second optical sensor row between which a planar object to be measured is placed. The direction of the first sensor row and the direction of the second sensor row differ from one another. Each sensor of the first sensor row forms data representing a distance between the object to be measured and the sensor. Each sensor of the second sensor row forms data representing a distance between the object to be measured and the sensor in order to determine at least one property of the object to be measured on the basis of the data.

  • Measuring instrument and method for determination of the properties of an item and its surface
    Patent number: 8786836
    Abstract: A measurement device for the determination of the characteristics of the object's surface by means of the optical radiation, wherein a measurement device comprises an optical radiation source and a detector to receive the radiation reflected from the surface being measured. In addition, a measurement device comprises an emitted optical radiation processing unit, which is adjusted to split optical radiation emitted by an optical source into separate wavelengths and to direct said separate wavelengths to the object being measured in a direction, that differs from the normal of the surface being measured so, that at least the shortest and the longest wavelengths of said wavelengths are focused on different halves and different heights of the measured object's surface, in the direction of the normal of the surface being measured.
