Advancing Industrial Imaging: Contactless THz Domain Spectroscopy for Topography and Chemistry

Year: 2024

Type: article

Abstract: This research introduces a dual-functional contactless imaging technique based on terahertz time domain spectroscopy (THz-TDS) for simultaneous topographic and chemical analysis. The method was tested on pharmaceutical and food industry samples, providing accurate non-destructive measurements of thickness, roughness and chemical composition. The results demonstrate its potential for real-time quality control on industrial production lines.
