5. Ultrahigh-Resolution Transversal Polarization-Sensitive Optical Coherence Tomography: Structural Analysis and Strain-Mapping

   SpringerLink Home (Jan 11 2008) Non-Medical Explore Article

   Abstract Optical coherence tomography (OCT), originally developed and so far nearly exclusively used for biomedical applications (e.g., [1,2]), is a contact-free, non-destructive technique based on low-coherence interferometry to image structures within translucent and turbid materials. Commonly, cross-sectional reflectivity images with a depth-resolution determined by the coherence length of the near-infrared light source are obtained. When OCT is performed in a polarization sensitive way (PS-OCT), additional information about birefringence within a ... (Read Full Article)

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

   NDT Database & The e (Nov 5 2007) Non-Medical Explore Article

   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)

7. Beyond biomedicine: a review of alternative applications and developments for optical coherence tomography

   SpringerLink Home (Jun 28 2007) Non-Medical Explore Article

   Optical coherence tomography (OCT), a method for depth-resolved imaging within turbid media based on the concept of low-coherence interferometry, rapidly evolved in the recent years with the development of a multitude of new functionalities and modalities. Biomedical research and diagnostics have been up to now the main driving forces for the reported applications and progress in OCT. The characteristics of OCT, precisely the ability to provide high-resolution images in a ... (Read Full Article)

8. Investigation of glass–fibre reinforced polymers by polarisation-sensitive, ultra-high resolution optical coherence tomography: Internal structures, defects and stress

   ScienceDirect (May 22 2007) Non-Medical Explore Article

   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)

9. Transversal ultrahigh-resolution polarizationsensitive optical coherence tomography for strain mapping in materials

   opticsinfobase.org (Jun 26 2006) Non-Medical Explore 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)

11. Non-destructive quantification of internal stress in polymer materials by polarisation sensitive optical coherence tomography

    ScienceDirect (Apr 7 2005) Non-Medical Explore Article

    Polarisation sensitive optical coherence tomography (PS-OCT) is an interferometric technique to determine and map the internal birefringence properties of translucent and turbid samples. Because of its non-destructive character, PS-OCT is an ideal method for material characterisation and testing. When birefringence patterns induced by mechanical strain are analysed, information about the stress within a material can be obtained. In this work, we investigate the stress in polymer samples using PS-OCT. From ... (Read Full Article)

13. Polarisation-sensitive optical coherence tomography for material characterisation and strain-field mapping

    SpringerLink Home (Apr 1 2003) Non-Medical Explore Article

    Optical coherence tomography (OCT) is a relatively new imaging technique capable of recording cross-sectional images of transparent and turbid structures with micrometer-scale resolution. Originally developed for biomedical imaging applications, this technique also has a great potential for non-destructive material characterisation and testing. Polarisation-sensitive (PS) OCT is a recent extension of classical OCT that measures and images birefringence properties of a sample, which, however, has not yet been applied to materials ...
