Terahertz compute tomography for 3D volume analysis of sample.

Processing sequence for non-destructive inspection based on 3D terahertz images

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…

Terahertz radiation for tomographic inspection

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…
