Journal ArticleDOI

Terahertz imaging and tomography as efficient instruments for testing polymer additive manufacturing objects.

Jean-Baptiste Perraud, +7 more
- 01 May 2016 - 
TL;DR: Terahertz (THz) imaging is demonstrated as an innovative method for 2D inspection of polymer materials and may be considered as an alternative to x-ray tomography and cheaper 3D imaging for routine control.
Journal ArticleDOI

Advanced Processing Sequence for 3-D THz Imaging

Hugo Balacey, +5 more
- 08 Feb 2016 - 
TL;DR: In this article, an advanced image processing sequence is presented to perform nondestructive inspection from 3D terahertz (THz) images, which leads to 3D visualization and dimensional measurements.
Journal ArticleDOI

Ordered subsets convex algorithm for 3D terahertz transmission tomography

Benoit Recur, +6 more
- 22 Sep 2014 - 
TL;DR: A new reconstruction method in order to perform 3D Terahertz tomography using a continuous wave acquisition setup in transmission mode based on the Maximum Likelihood for TRansmission tomography (ML-TR) first developed for X-ray imaging is investigated.
Journal ArticleDOI

Shape-from-focus for real-time terahertz 3D imaging.

Jean-Baptiste Perraud, +5 more
- 01 Feb 2019 - 
TL;DR: The shape-from-focus algorithm is a post-processing tool used in optical microscopy to reconstruct the external shape surface of a convex surface object and an application of this algorithm in active and real-time terahertz imaging is proposed.
Journal ArticleDOI

Terahertz phase retrieval imaging in reflection.

Nikolay V. Petrov, +5 more
- 01 Aug 2020 - 
TL;DR: This Letter demonstrates the implementation oferahertz phase retrieval in reflection geometry with a continuous wave acquisition system working at 0.287 THz and proposes a double parallel recording scheme with one detector and two lock-in amplifiers operating with the complimentary sensitivity setting.
