Multispectral Terahertz Imaging System Incorporates Neural Network
LOS ANGELES, Jan. 29, 2024 — Researchers at UCLA have developed a focal plane array (FPA) capable of supporting real-time multispectral terahertz (THz) video in 3D. According to the team, led by UCLA professors Mona Jarrahi and Aydogan Ozcan, this is the first time a terahertz imaging system has been able to achieve real-time multispectral imaging with video capability while maintaining a high signal-to-noise ratio (SNR). The THz spectrum is desirable due to its ability to penetrate opaque materials and provide

Terahertz Imaging System on a Chip Offers Speed and Portability
PRINCETON, N.J., July 29, 2019 — An imaging system developed at Princeton University uses lasers small enough to fit on a microchip, and emits and detects electromagnetic radiation at terahertz (THz) frequencies. The new system, which is based on a semiconductor design, uses a...
Time-Resolved Technique Could Provide High Resolution for THz Imaging
BRIGHTON, England, Aug. 30, 2018 — Using a single-pixel camera operating at THz frequencies, researchers at the University of Sussex have discovered a way to capture with a high degree of accuracy not just the shape of an object, but also its chemical composition. The technique uses...
Terahertz Window Offers Untapped Potential
Oct 3, 2017 — Sandwiched between the infrared and microwave parts of the electro-magnetic spectrum lies the terahertz window — a valuable and largely untapped portion of energy that can reveal a huge variety of unknowns, from hidden weapons and suspicious...
Subwavelength THz Could Improve Image Resolution, Accelerate Imaging Speed
EXETER, England, Sept. 5, 2017 — A terahertz (THz) imaging technique that is compatible with adaptive and compressive sensing algorithms has been developed and has demonstrated image reconstruction at highly subwavelength dimensions. Using a near-field approach to THz imaging,...
Breakthroughs Bring THz Spectroscopy, Sensing Closer to Mainstream
Nov 3, 2016 — The terahertz (THz) electromagnetic spectrum (1 to 10 THz), sitting between the infrared wavelengths on the higher frequency side and microwaves on the lower frequency side, has unique and important properties. THz waves can pass through a number of...
More Practical THz Imaging on the Horizon
CAMBRIDGE, Mass., May 6, 2014 — A new theory offers to reduce the number of sensors required for high-resolution terahertz and millimeter-wave imaging, potentially making it more practical.

New Technique Boosts Speed of THz Imaging
KAWASAKI, Japan, Sept. 20, 2011 — A new twist on terahertz imaging promises to speed inspections by a factor of 25. As a result, this technology has potential applications in airport security, narcotics investigations and electronic devices inspections. An existing measurement...
THz Technique is ‘All-Optical’
TROY, N.Y., July 26, 2010 — A team of Rensselaer Polytechnic Institute researchers has opened the way for detecting hidden explosives, chemical, biological agents and illegal drugs from a distance of 20 m using terahertz (THz) wave technology. The new, all-optical system has...
T-rays Reveal Hidden Art
ANN ARBOR, Mich., Feb. 4, 2008 -- A device that combines lasers and electronics uses pulses of terahertz radiation -- T-rays -- to reveal depth and detail in a way x-rays cannot, and could let art historians see murals hidden beneath coats of plaster or paint in centuries-old...
Photonics Inspects Space Shuttle
Nov 1, 2005 — Before starting out on a long trip, travelers examine their vehicle to make sure there will be no problems, particularly important when the mode of transportation is as complex as the space shuttle and the destination as exotic as space. For the...
