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 ...

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.

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 …

2020年1月1日 · THz images are preprocessed using texture features (gray level co-occurrence matrix GLCM) and invariant moment algorithm. Both KNN and artificial neural network (ANN) are used for classification of the normal and the abnormal breast tissues.

2022年5月24日 · Terahertz Science Database (TSD) is an open initiative to allow Terahertz Community to share raw data, measurements, images, and more widely terahertz resources, in order to promote multidisciplinary fruitful collaborations.

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.
