The research presents a novel, rapid diagnostic technique that harnesses terahertz (THz) pulse time‑domain holography to evaluate the optical properties of lyophilized blood plasma pellets. By converting plasma into compact, freeze‑dried tablets, the method overcomes the limitations of liquid blood…
The work demonstrates, for the first time, a practical, single‑beam terahertz (THz) phase‑retrieval imaging system that operates in a reflection configuration at a continuous‑wave frequency of 0.287 THz. By recording the reflected intensity at 27 axial positions and combining the signals from two…
Terahertz (THz) imaging and tomography have been shown to provide a rapid, non‑destructive and radiation‑free method for inspecting polymer parts produced by additive manufacturing. Unlike conventional X‑ray tomography, THz techniques offer the possibility of routine quality assurance for complex…
Terahertz (THz) imaging exploits the unique ability of 0.3–10 THz radiation to penetrate a wide range of dielectric materials while providing spectroscopic fingerprints of many chemical species. The reviewed work demonstrates that, beyond conventional two‑dimensional transmission or reflection…
Terahertz (THz) imaging offers a non‑destructive, contactless method for probing the internal structure of dielectric materials, yet its practical use has been limited by severe artifacts caused by refractive‑index mismatch at sample interfaces. This study demonstrates that immersing non‑planar…
An in-depth editorial guide to Single-scan multiplane phase retrieval with a radiation of terahertz quantum cascade laser, its scientific context, terahertz contribution, applications, and collaboration potential in Biomedical Imaging.
Executive Summary This research introduces a novel algorithm—Multiplane Iterative Phase Retrieval with Inpainting (SBMIR‑I)—that corrects for over‑exposure in terahertz (THz) diffraction imaging. By automatically “inpainting” saturated regions in the measured intensity data, the algorithm…
The study demonstrates a fully integrated, real‑time terahertz computed tomography platform that can acquire full‑field images at 25 frames per second, reconstruct a three‑dimensional volume, and automatically process that data to reveal detailed internal morphology within a single minute. By…
An in-depth editorial guide to An algorithm of unordered wavefront propagation in terahertz phase retrieval with dense multiplane data acquisition, its scientific context, terahertz contribution, applications, and collaboration potential in Biomedical Imaging.
This article focuses on improving diffraction imaging techniques in the field of Térahertz frequencies, by approaching the problem of data saturation due to the limited dynamic range of detection systems. We introduce with the ITMO team (Nikolay V Petrov Team) a new approach to algorithmic reconstruction which deals with saturated areas in the measured intensity … Read more
Collaboration with ITMO University about Terahertz After the visit of the great museum of optics in ITMO, Saint Petersbourg, Russia, an interesting discussion started with ITMO colleagues about terahertz phase retrieval and holography. We were also pleased to invite Nicholay Petrov at IMS Laboratory in Bordeaux. I am delighted to present here the results of … Read more
