Abstract: A novel measurement of roll profile is introduced, and the
composition and the error compensation analysis of this system are
present. The testing method of the system is based on the sonic
circulation and multi-pulse echo technique which can conquer the
limitation of pulse-echo times and improve the accuracy of measurement.
Experiment indicates the standard deviation of measure data is 7.69 μm.
It seems that it will get well applications foreground in the field of
roll profile measurement.
Key words: Sonic circulation Multi-pulse echo technique Roll profile
measurement Error compensation Relative measurement
