Together with Yaochun Shen at the University of Liverpool and our industrial collaboration partners we have developed a terahertz sensor for non-contact thickness and quality measurement of automobile paints.
The technology is suitable to measure the thickness of complex stacks of paints (electro coat, primer, base coat and clear coat) on both metallic panel or carbon fibre panel. We were able to demonstrate that the technique is able to quantitatively resolve the thickness of thin layers of less than 30 μm thickness and that these measurements can be made for metallic, pearlescent and normal base coats alike.
