Efficient photoconductive terahertz detection through photon trapping in plasmonic nanocavities
APL Photonics, 2021 We present a photoconductive terahertz detector that employs a plasmonic nanocavity to offer high-sensitivity and broadband operation when used in a terahertz time-domain spectroscopy system even at very low optical pump power levels.

Hybrid Sparsity Model for Fast Terahertz Imaging
Micromachines, 2021 In order to shorten the long-term image acquisition time of the terahertz time domain spectroscopy imaging system while ensuring the imaging quality, a hybrid sparsity model (HSM) is proposed for fast terahertz imaging in this paper, which incorporates ...

Terahertz Time-Domain Spectroscopy of Human Blood [PDF]
IEEE Journal of Biomedical and Health Informatics, 2013 In the continuing development of terahertz technology to enable the determination of tissue pathologies in real-time during surgical procedures, it is important to distinguish the measured terahertz signal from biomaterials and fluids, such as blood, which may mask the signal from tissues of interest.

Terahertz imaging: a new non-destructive technique for the quality control of plastic weld joints [PDF]
Journal of the European Optical Society-Rapid Publications, 2007 We present the first investigation of plastic weld joints using terahertz waves. Terahertz time-domain spectroscopy clearly reveals contaminations like metal or sand within the weld joint of two high-density polyethylene sheets. Furthermore, areas can be
