The internationally patented TireChecker system is consisting of one or several laser light-sectioning sensors and a specialized PC based evaluation software enabling geometry measurements at high velocities. The software can acquire bumps, lateral contractions and radial and axial runouts with high speed and reliability. By using line lasers the measuring of tires becomes possible also on complex surfaces like letterings or symbols. Thus, the extension of bumps and lateral contractions can be determined in all three dimensions.
In light-sectioning a light-section is projected onto the surface of a tire and monitored by a specialized camera under an angle from the projection direction. From the course of the light section a height profile is generated. By rotating the tire within one second thousands of height profiles of the surface are recorded.
