A process for determining properties of a traveling material web comprising:
- simultaneously illuminating a plurality of measuring points on the material web with electromagnetic radiation;
- and
- imaging, through at least one optical device, the plurality of measuring points on one detection surface of at least one detector,
- wherein the electromagnetic radiation is within the IR range.
A apparatus for determining properties of a traveling material web comprising:
- at least one radiation source for illuminating, in the IR range, a plurality of measuring points on the material web;
- at least one detector having a detection surface;
- and
- at least one optical device for imaging of the measuring points on the detection surface of the at least one detector.
A apparatus for determining properties of a traveling material web comprising:
- at least one radiation source for illuminating a plurality of measuring points on the material web;
- at least one detector having a detection surface having a plurality of pixels;
- at least one optical device for imaging of the measuring points on the detection surface of the at least one detector;
- said at least one optical device comprising a plurality of optical fibers, wherein each optical fiber is assigned to a respective measuring point;
- said plurality of optical fibers comprising entrance surfaces positioned adjacent said respective measuring point, and emergent sides coupled to provide images of the measuring points on said detection surface;
