1. Advanced Optical Coherence Tomography techniques: novel and fast imaging tools for non-destructive testing

   Explore Article NDT Database & The e (Oct 25 2008) NDE/NDT

   We demonstrate that Optical Coherence Tomography (OCT), a method which was originally developed for depth-resolved imaging of biological tissue, is suited to adequately respond to different problems posed in the field of contactless material characterisation and non-destructive testing and evaluation. In detail, the potential of advanced OCT techniques like ultrahigh-resolution OCT, polarisation-sensitive OCT or spectral-domain OCT is evaluated and exemplified for the imaging and characterisation of different polymer and ceramic ...

2. Modern Non-Destructive Physical Methods for Paintings Testing and Evaluation

   Explore Article NDT Database & The e (Oct 14 2008) Art

   There are several rapidly developing non-destructive physical methods that are increasingly used for the analysis and assessment of art objects. These technologies are posed to bring about drastic changes in the attribution and inventory characterization procedures carried out by museums, private collections, art dealers, and art community as a whole. Certainly today nondestructive evaluation (NDE) of art objects is becoming more and more sophisticated. The applications of these methods include ... (Read Full Article)

3. Optical Coherence Tomography for Non-Destructive Investigations of Structure of Objects of Art

   Explore Article NDT Database & The e (Oct 14 2008) Art

   In this contribution the Optical Coherence Tomography (OCT), as a novel tool for non-invasive structural imaging of selected objects of cultural heritage, will be reviewed. This technique relies on multispectral interference o f infrared light and therefore is well suited for investigation of transparent and semi-transparent structures. The technique originates from medical imaging and has been present in conservation science since 2004. Until now it has been successfully utilized in ... (Read Full Article)

4. Spectral-Domain Optical Coherence Tomography: a Novel and Fast Tool for NDT

   Explore Article NDT Database & The e (Nov 5 2007) NDE/NDT

   Spectral-domain Optical Coherence Tomography (SD-OCT) is a new, promising variant of OCT, providing superior sensitivity and measurement speed for cross-sectional imaging of turbid materials. OCT, originally developed for applications in the field of biomedical diagnostics, has shown high potential for other non-biomedical investigation tasks, e.g. within the field of non-destructive testing (NDT) and contactless material characterization. However, mostly standard OCT techniques have been used for these applications. Therefore, we demonstrate ... (Read Full Article)
