Terahertz Time-Domain Spectroscopy

The Terahertz (THz) frequency regime, also referred to as the sub-millimeter wave or far-infrared radiation, commonly spans a broad range from 100 to 6000 GHz. Being a blank spot on the available energetic radiation map for many years, newer developments have pushed terahertz to a rapidly emerging technology and to the forefront of innovative, photonic applications in fundamental sciences but also for real-world applications, applied in the spectroscopy or imaging of novel materials and non-destructive investigations. The THz webinar provides a fair understanding of the fundamental science of terahertz electrical field generation and detection, with a distinct focus on pulsed, broadband time-domain terahertz spectroscopy (THz-TDS) and imaging. We review the various technical approaches that enable THz-TDS measurements highlighting their outstanding merits in the vicinity if spectroscopic and imaging solutions but also discuss the pitfalls of terahertz. Particularly, we draw attention to the cross-disciplinary, multi-purpose use of terahertz TDS providing time-of-flight information on the one hand and spectroscopic details of examined samples at the same time. In this regard, we take a snapshot of current and future application examples ranging from research to industry. We demonstrate a live-setup to our audience.

The THz workshop provides a basic understanding of the different technical principles of generation and detection and snapshots current application fields. It is thus addressed to all participants from different degrees interested in exploring a new, promising technology. Attendees to whom THz-TDS can be particularly of practical need include the following fields (but are not limited to!): Physics, Electrical Engineering, Nanotechnology, Chemistry, Biology, Pharmacy, Automotive, Semiconductor Industry, Non-destructive testing, Spectroscopy and Medical Sciences.
