“…An early attempt in this direction has been reported by Hermann and coworkers who used an array of eight photoconductive antennas [318]. In 2008 Pradarutti et al demonstrated a line array of 16 elements coupled to a microlens array that generates 16 single spots from the exciting fs-laser beam [319]. Very recently, Picometrix demonstrated a hand-held, high-speed THz-TDS reflection line-scanner [320].…”

Over the past three decades a new spectroscopic technique with unique possibilities has emerged. Based on coherent and time-resolved detection of the electric field of ultrashort radiation bursts in the far-infrared, this technique has become known as terahertz time-domain spectroscopy (THz-TDS). In this review article the authors describe the technique in its various implementations for static and time-resolved spectroscopy, and illustrate the performance of the technique with recent examples from solid-state physics and physical chemistry as well as aqueous chemistry. Examples from other fields of research, where THz spectroscopic techniques have proven to be useful research tools, and the potential for industrial applications of THz spectroscopic and imaging techniques are discussed.

“…So a complete THz image has to be recorded. As the development of multipixel THz systems with spectroscopic capabilities is still an ongoing process, [52] we will introduce a technique relying on the rapid scanning of one pixel and a relative movement of the object, the so-called raster scanning imaging.…”

Terahertz Time‐Domain Spectroscopy of Gases, Liquids, and Solids

The techniques and methods employed in the spectroscopic characterization of gases, liquids, and solids in the terahertz frequency range are reviewed. Terahertz time-domain spectroscopy is applied to address a broadband frequency range between 100 GHz and 5 THz with a sub-10 GHz frequency resolution. The unique spectral absorption features measured can be efficiently used in material identification and sensing. Possibilities and limitations of fundamental and industrial applications are discussed.

“…A combined sensor would be expected to be laboratory based initially, due to the scanning and source requirements of the terahertz sensor. Recent developments show that the scan speed of the THz sensor can be accelerated using a higher number of detection pixels [30]. Also a more optimized THz-optic would be necessary to get a homogeneous illumination of the sample without stripes in the analyzed data.…”
