In this paper, we study of the impact of low-frequency noise on terahertz-computed tomography (THz-CT). Two acquisition methods are compared in order to analyze how the low frequency noise is projected into the 3D image after reconstruction.
In this paper, a processing sequence has been developed to achieve automated analysis and measurements from 3D terahertz acquisitions. This sequence first performs a tomographic reconstruction from a 3D acquisition made by a continuous millimetre wave system. This reconstruction is based on the Ordered Subsets Convex (OSC) algorithm and has been optimized for 3D THz…
This paper presents terahertz non destructive test of 3D printed materials in the framework of MetAMMI project.
Ordered Subsets Convex (OSC) implementation for terahertz waves and comparison of the quality and the accuracy with other tomographic reconstructions.
This paper demonstrate how it is possible to take into account the physical properties of THz waves used in THz CT scan imaging as an improved beam propagation model. This more realistic model is clearly justified by the fact that previous models were simply relying on well-known and commonly applied X-ray reconstruction methods, which assume…
