In this collaborative article between Lytid, IMS and Noctylio, we explore the application of terahertz (THz) technology in tomography to create 3D reconstructions in real time. The experimental setup is based on a latest generation micro-bolometric camera with 240×320 pixels, equipped with an anti-reflective coated lens developed by Lytid, to record the projection images of…
This article examines the possibility of using a high frequency radar (300 GHz) to detect fractures and lithological changes in rocks. This study, carried out in collaboration between Federico Sanjuan (University of Pau, France) and the IMS laboratory (University of Bordeaux), is in the context of the improvement of the methods of detection and quantification…
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…
