Experimental Assessment of the Applicability of Laser Triangulators for Measurements of the Thickness of Hot Rolled Product

  • Published:
Measurement Techniques Aims and scope

Results from an experimental assessment of the applicability of laser triangulators for measurements of the thickness of hot rolled product are presented. It is shown that phase inhomogeneities caused by strong temperature gradients introduce serious distortions into the optical signals of laser triangulators, which ultimately substantially increase the error.
