3. Applicability of Optical Coherence Tomography at 1.55 μm to the Examination of Oil Paintings

   Explore Article SpringerLink Home (Aug 9 2009) Art

   With 47 samples of commercially available oil paints, the applicability of Optical coherence tomography to noninvasive tomography of paint layers was examined. Two different instruments, utilizing near-infrared light with central wavelength of 823nm and, for the first time, 1.55 μm, were used to obtain cross-sectional images. Example tomograms are given; a ray tracing correction of images is also discussed. The tests revealed that applicability of OCT is limited to certain ... (Read Full Article)

4. An investigation of the accelerated thermal degradation of different epoxy resin composites using x-ray micro computed tomography and optical coherence tomography

   Explore Article ScienceDirect (Jun 27 2009) NDE/NDT

   Epoxy resin composites reinforced with hollow glass microspheres, microlight microspheres, 3D parabeam glass, and E-Glass individually were subjected to accelerated thermal degradation conditions. X-ray micro computed tomography (XμCT) was used to evaluate density changes, reinforcement filler damage, homogeneity, cracks and microcracks in the bulk of the different epoxy resin composites. XμCT 3D images, 2D reconstructed images and voids calculations revealed microspheres damage, filler distributions and showed cracks in all composites ... (Read Full Article)

   Explore Article SPIE Digital Library (Feb 18 2009) Ophthalmology

   Polarization-sensitive (PS) optical coherence tomography (OCT) allows for depth-resolved measurement of light polarizing properties of different layers in the human retina. Since their inherent polarizing properties are different, the retinal structures can be identified using PS-OCT. We present an ... [Proc. SPIE 7163, 71630N (2009)] published Wed Feb 18, 2009.

7. Spatially Resolved Stress Measurements in Materials with Polarisation-Sensitive Optical Coherence Tomography: Image Acquisition and Processing Aspects

   Explore Article www3.interscience.wiley.com (Dec 21 2008) NDE/NDT

   Abstract: We demonstrate that polarisation-sensitive optical coherence tomography (PS-OCT) is suitable for mapping the stress distribution within materials in a contact-free and non-destructive way. In contrast to transmission photoelasticity measurements, the samples do not have to be transparent but can be of scattering nature. Denoising and analysis of fringe patterns in single PS-OCT retardation images are demonstrated to be the bases for a quantitative whole-field evaluation of the internal stress ...

    In this paper, we report on optical coherence tomography (OCT) for the investigation of glass–fibre reinforced polymer (GFRP) materials. OCT, a contactless and non-destructive imaging technique, provides depth-resolved information on internal structures within semi-transparent materials. In our study, we apply a highly advanced OCT technique: we use a transversal scanning, ultra-high resolution, polarisation-sensitive (UHR-PS)-OCT for the analysis of various GFRP samples. UHR-imaging with resolution in the micron range is shown ... (Read Full Article)

    Optical coherence tomography (OCT) and its extension, polarization-sensitive (PS-)OCT, are techniques for contactless and non-destructive imaging of internal structures. In this work, we apply PS-OCT for material characterization. We use a transversal scanning, ultra-high resolution (UHR-)PS-OCT setup providing cross-sectional as well as in-plane information about the internal microstructure, the birefringence and the orientation of the optical axis within the material. We perform structural analysis and strain-mapping for different samples: we ... (Read Full Article)
