FIELD: measurement equipment.
SUBSTANCE: in the method of triangular measurement of thickness of sheet products they feed a sheet product into a measurement area, and probing beams of radiation are directed to the product at two opposite sides with the help of sources of radiation of optical systems, at least three from each side of the product. Sources of radiation of optical systems are aligned in such a manner that probing beams at the opposite sides of the sheet product form tops of crossing convex polygons. Thickness of the sheet product is calculated as distance between polygons at the opposite sides of the sheet product in the field of their crossing. The method of triangular measurement of thickness of sheet products makes it possible to measure thickness of the sheet product in case of its random orientation in the measurement volume.
EFFECT: increased accuracy of detection of sheet product thickness.
