Terahertz to bits and bits to terahertz [PDF]
Proceedings of the 7th ACM International Conference on Nanoscale Computing and Communication, 2020 The high millimeter-Wave and Terahertz spectrum above 100 GHz will form the underpinning of a broad set of game-changing future technology including high resolution sensing, imaging, robotics, autonomous systems, and wireless communication. In the last decade, we have seen a tremendous surge in efforts towards enabling chip-scale technology to address ...

Optics Letters, 2018 We realized a phase retrieval technique using terahertz (THz) radiation as an alternative to THz digital holography, named THz ptychography. Ptychography has been used in x-ray imaging as a groundbreaking improvement of conventional coherent diffraction imaging. Here we show that ptychography can be performed at THz frequencies too. We reconstructed an

Optics Express, 2012 The ability to retrieve information from different layers within a stratified sample using terahertz pulsed reflection imaging and spectroscopy has traditionally been resolution limited by the pulse width available. In this paper, a deconvolution algorithm is presented which circumvents this resolution limit, enabling deep sub-wavelength and sub-pulse ...

Journal of Biomedical Optics, 2011 We present an overview and history of terahertz (THz) sources for readers of the biomedical and optical community for applications in physics, biology, chemistry, medicine, imaging, and spectroscopy. THz low-frequency vibrational modes are involved in many biological, chemical, and solid state physical processes.

Subsurface Sub-terahertz and Terahertz Tomography
PIERS Online, 2010 Development of millimeter and sub-millimeter wavelengths technologies is one of the most promising research areas, especially for applications in so called terahertz imaging. In the paper we consider a tomography approach for obtaining 3-D imaging in frequency range from 100 GHz up to 325 GHz.

Terahertz single pixel imaging based on a Nipkow disk [PDF]
, 2012 We describe a terahertz single pixel imaging system based on a Nipkow disk. Nipkow disks have been used for fast scanning imaging systems since the first experimental television was invented in 1926.
