Towards industrial inspection with THz systems

Abstract

Due to their high spatial resolution, THz imaging systems (based on time domain spectrometers) have a broad variety of applications in scientific as well as industrial applications in the future—especially through the upcoming of reliable titanium sapphire lasers and fiber amplified femtosecond lasers. With such THz scanning highly sensitive measurements of materials as well as physical phenomena and simultaneously real-time imaging with real-time data extraction can be realized which can be used for production monitoring and/or more accurate and novel inlsine control systems. The article gives an overview on recent state of the art THz systems based on femtosecond lasers and their application scenarios, like detection.
