    2. Evaluation of selective laser sintering processes by optical coherence tomography

      Evaluation of selective laser sintering processes by optical coherence tomography
      Selective laser sintering (SLS) enables the fast, flexible and cost-efficient production of parts directly from 3D CAD data. Unlike more established machine tools, there is a marked lack of process monitoring and feedback control of key process variables. In-situ analysis techniques permit the emergence of repair techniques, in-process optimization of production parameters, and will also serve to save time and material. In this study, optical coherence tomography (OCT) is used ...

    3. Feature Of The Week 8/25/13: Anti-biofouling Conducting Polymer Nanoparticles as a Label-Free Optical Contrast Agent for High Resolution Subsurface Biomedical Imaging

      Feature Of The Week 8/25/13: Anti-biofouling Conducting Polymer Nanoparticles as a Label-Free Optical Contrast Agent for High Resolution Subsurface Biomedical Imaging
      Optical coherence tomography (OCT) is a modern optical imaging technique that has been widely use in ophthalmic imaging for more than a decade. There has been increasing interest in extending its imaging applications to include other sub-surface biomedical imaging applications (e.g. cancer diagnosis). However, poor image contrast caused by multiple light scattering is a major challenge for OCT imaging in heterogeneous poorly transparent tissues (e.g. skin). We report ...

    5. Optical measurement of the structure of articular cartilage

      Optical measurement of the structure of articular cartilage
      A new optical technique can non-invasively determine the collagen structure in articular cartilage and could lead to improved understanding of arthritis. Medical conditions such as osteoarthritis are painful, debilitating, and hard to treat because they involve degradation of tissues that have a poor natural repair capacity, such as articular cartilage (which coats the sliding surfaces of articulating joints such as the knee). Cartilage is a material with remarkable mechanical properties ...

    6. Feature Of The Week 5/6/12: University of Sheffield investigates models to study the 3D structural orientation of the collagen fibers in articular cartilage using PS-OCT

      Feature Of The Week 5/6/12: University of Sheffield investigates models to study the 3D structural orientation of the collagen fibers in articular cartilage using PS-OCT
      Researchers from the University of Sheffield recently showed the applicability of an extended Jones matrix calculus approach to understand the 3D orientation information of collagen fiber in articular cartilage using multi-angle polarization sensitive optical coherence tomography OCT imaging.  The work could potentially advance the use of OCT imaging in orthopaedics and improve our understanding of the biomechanics and pathological changes occurring in articular cartilage during osteoarthritis.For more information see ...

    8. Polarization-sensitive optical coherence tomography using continuous polarization modulation with arbitrary phase modulation amplitude

      Polarization-sensitive optical coherence tomography using continuous polarization modulation with arbitrary phase modulation amplitude
      We demonstrate theoretically and experimentally that the phase retardance and relative optic-axis orientation of a sample can be calculated without prior knowledge of the actual value of the phase modulation amplitude when using a polarization-sensitive optical coherence tomography system based on continuous polarization modulation (CPM-PS-OCT). We also demonstrate that the sample Jones matrix can be calculated at any values of the phase modulation amplitude in a reasonable range depending on ...

    9. Optical coherence tomography based angle-resolved backscattering studies on bovine tendon and cartilage

      Optical coherence tomography based angle-resolved backscattering studies on bovine tendon and cartilage
      The difference in the genetic make up of the constituent molecules in collagen fibers in tendon and articular cartilage is what makes them mechanically and functionally different. A comparative study carried out on the differences in the angle-resolved back-scattering properties obtained from optical coherence tomography based studies on the two different types of scatterers: collagen I and collagen II fibers in bovine tendon and bovine articular cartilage sample, respectively, is ...
