| Zusammenfassung | In this paper, we demonstrate the suitability of terahertz time domain spectroscopy for thickness measurements of acrylate based coatings on polyester fabric. First, we spectroscopically analyze the materials involved using a high precision terahertz spectrometer and determine optical properties such as refractive index and absorption coefficient. We then perform raster scans across the sample and create terahertz images to identify material boundaries and thickness inhomogeneities. Finally, we apply a fast scanning terahertz time domain spectrometer based on electronically controlled optical sampling and a customized reflection head for online thickness measurements in a coating line. The textile mov es at a speed of 0 5 m/min while the measurement system records terahertz pulses at a rate of 1600 traces/sec. Coating thicknesses between 6 3 µm and 9 9 µm are calculated in one post processing step. We compare these non contact and non destructive measurements with results obtained from standard methods. |
