    3. Feature Of The Week 12/13/09: Using Optical Coherence Tomography to Study Wood and Wood Finishes on an 18th century Italian violin

      Feature Of The Week 12/13/09: Using Optical Coherence Tomography to Study Wood and Wood Finishes on an 18th century Italian violin
      Feature Of The Week 12/13/09: When available, non-contact, non-destructive and in situ techniques are very much favoured to study the cultural heritage artefacts that are precious witnesses of the past, by limiting the number of micro-samples. Optical Coherence Tomography (OCT) is then especially attractive. OCT potentially allows a better representativity than techniques which require a sample, by increasing the number of instruments studied and the number of measurements on each instrument. During the past few years, many applications of OCT have been reported in the field of art technology and art conservation. An original full-field time-domain OCT system ...

      Feature Of The Week 12/6/09: Cascaded Wavelength Swept Amplified Spontaneous Emission Source for Optical Coherence Tomography
      Feature Of The Week 12/6/09: Due to increasing interest in Optical Coherence Tomography (OCT) using wavelength swept lasers (SS-OCT), huge efforts have been made by both research and commercial organizations around the world to push the performance of such sources and with it OCT system capabilities. This includes sweep repetition rate, power, new wavelengths, coherence length, and more. One of the drawbacks of standard wavelength-swept lasers is the fact that lasing has to build up from amplified spontaneous emission repetitively within several roundtrips of the light, limiting the maximum achievable sweep speed. Dr. Robert Huber and other researchers ...

    5. Feature Of The Week 11/29/09: Optical Coherence Tomography Imaging of healthy skin, actinic skin and NMSC lesions

      Feature Of The Week 11/29/09: Optical Coherence Tomography Imaging of healthy skin, actinic skin and NMSC lesions
      Feature Of The Week 11/29/09: Optical coherence tomography applications in dermatology have faced somewhat of a challenge since, from some perspectives, skin was designed to keep light out. Skin cancer is a common form of cancer and although it is not in the top ten cancer killers, there are a large amount of resources being devoted to investigating suspicious liaisons and pathologies. For example, more than 1 million cases of non-melanoma skin cancer are diagnosed yearly in the United States. Melanoma, the most serious type of skin cancer, will account for about 70,000 cases of skin cancer ...

      Feature Of The Week 11/22/09: Development of Optical Coherence Tomography Point-Spread Function Test Artifacts
      Feature Of The Week 11/22/09: The Biophotonics group of the UK National Physical Laboratory is working on methods and phantoms to help with the uptake of OCT technology in to the medical and other industrial sectors. They are looking at the requirements for consistent and robust characterization methods to determine the fundamental system performance of OCT systems. An important baseline metric in this respect is the system 3D point-spread function (PSF) that ultimately limits the optical resolution of an instrument. Conventionally the lateral and axial resolutions can be determined independently for instance using reflective interfaces or optical test-charts ...

      Feature Of The Week 11/15/09: A Comparison between Optical Coherence Tomography and Histology of Laryngeal Epithelial Thickness
      Feature Of The Week 11/15/09: While applications of optical coherence tomography in ophthalmology and cardiology have very successfully transitioned from the research world to the commercial world many other fields have lagged behind. One such area is the field of Otolaryngology. While much of the technology developed in both the academic and commercial worlds is directly applicable to applications in otolaryngology there remain some unique features such as probe design and a need for additional clinical data to determine where OCT will be most beneficial. Numerous researchers around the world are working in this field. Researchers from the ...

      Feature Of The Week 11/08/09: Application of wavelet analysis in optical coherence
      Feature Of The Week 11/08/09: Optical Coherence Tomography (OCT) is modern optical diagnostic technique, which is well suited for non-invasive imaging of the interior structures of dense media from a range of composite materials to biological tissues. Since OCT is known for being able to reject multiple scattering, it has been used successfully to image low scattering samples such as retina to considerably scattering samples such as biological tissues and synthetic scaffolds. However, with some highly scattering samples OCT struggles to cope with multiple scattering resulting in a rather poor quality of images. In order to improve the ...

    13. Feature Of The Week 11/1/09: Dual-Fiber Stretcher as a Tunable Dispersion Compensator for an All-Fiber OCT Systems

      Feature Of The Week 11/1/09: Dual-Fiber Stretcher as a Tunable Dispersion Compensator for an All-Fiber OCT Systems
      Feature Of The Week 11/1/09: Over the past decade, OCT has been implemented with widely different geometries, including both free-space and fiber components. Fiber-based OCT systems are advantageous in terms of being low-cost, lightweight, stable, compact and portable. Most fiber systems still rely, however, on some free-space components, most notably in the optical delay line. The challenge here is that optical fibers often introduce a significant chromatic dispersion mismatch between the two arms of the interferometer, which unless properly compensated broadens the point-spread function (PSF) and degrades the axial resolution. Dispersion can in principle be canceled by adjusting ...

      Feature Of The Week 9/27/09: Collective Dynamics of Swimming Bacteria: OCT Studies

      Feature Of The Week 9/27/09: Physical mechanisms governing large-scale organization of self-propelled biological microparticles, such as motor proteins, swimming bacteria, and other motile cells, attract significant attention among physicists and biologists. Scientists from Argonne National Laboratory, Imalux, and Cambridge University, discovered that commonly found bacteria such as Bacillus Subtilis are in fact highly efficient mixers for the liquid they live in. Thanks to original non-invasive optical coherence tomography developed by Imalux Corporation, OH, the scientists observed with unprecedented precision the phenomena unfolding in the liquid containing the bacterial suspension. The measurements revealed up to 100-fold increase of mixing ...
