2020年5月21日 · Terahertz (THz) radiation is poised to have an essential role in many imaging applications, from industrial inspections to medical diagnosis. However, commercialization is...

2023年9月15日 · Here, we review the development of terahertz imaging technologies from both hardware and computational imaging perspectives. We introduce and compare different types of hardware enabling...

Concealed object detection in Terahertz imaging is an urgent need for public security and counter-terrorism. In this paper, we provide a public dataset for evaluating multi-object detection algorithms in active Terahertz imaging resolution 5 mm by 5 mm.

We present the THz 3-D imaging strategy using synthetic aperture radar (SAR) techniques, the related theoretical background and the experimental results in this paper. An active frequency-modulated continuous wave (FMCW) terahertz (THz) system has been developed to image objects in millimeter-scale resolution in three dimensions.

2021年9月22日 · THz image processing deals with the interaction of matters in the sub-millimetre wavelength band (ca. 300 GHz to 3 THz) of a distinct electromagnetic spectrum indistinguishable from the other spectroscopic techniques. The THz regime also known as the “THz gap” for a long time as neither microwave nor optical devices could entirely ...

Abstract: The paper introduces a new terahertz (THz) image benchmarking dataset for THz imaging. The degradation of THz image quality is one of the main problems caused by system noise, intrinsic long-wavelength, and diffraction phenomena. In this paper, the point spread function of the THz imaging process is reconstructed firstly.

2016年11月7日 · Here, we report THz-to-optical conversion using a gas of highly excited Rydberg atoms. By collecting THz-induced optical fluorescence we demonstrate a real-time image of a THz standing wave...

2024年11月1日 · Terahertz (THz) imaging is essential for non-contact and non-destructive testing due to its ability to penetrate numerous materials. Typically, the sample is raster-scanned through the beam waist of a confocal optical setup to generate an image in …

An open THz image repository. TSID (Terahertz Science Imaging Database) is open science, free to redistribute imaging database of THz measurements. It enables more collaboration activities between THz labs and data processing teams. It’s also a way to connect with other disciplines.

2023年1月4日 · Terahertz (THz) imaging is a non-invasive and high spatial-resolution technique that uses non-ionizing electromagnetic signals in a frequency range of 0.1–10 THz. Hence, this article focuses on diverse THz imaging techniques, THz antennas and designing methods, image reconstruction algorithms, and its applications.
