Résumé :	System tests on automotive coatings show the advantages of using terahertz radiation for coating thickness measurement. It allows each individual coating applied to a carbody to be measured and checked non-destructively. Even when the substrate is plastic.
Note de contenu :	- Detecting individual layers - Measuring irrespective of substrate - An automated measuring cell, fully integrated into the painting line : The system, which is mounted on a robot arm, measures without ever touching the surface - The measuring system checks all the paint layers on a carbody in a single work step - The measuring principle : The terahertz pulse penetrates several layers of paint and is partially reflected. The layer thicknesses can be calculated from the time it takes for the reflections to reach the detector
