    2. Method And Apparatus For Optical Coherence Tomography

      Method And Apparatus For Optical Coherence Tomography
      The invention relates to optical coherence tomography (OCT), more specifically to spectral optical coherence tomography (SOCT). The invention deals with problem of artefacts occurring in certain scan positions due to sharp increases of reflection by the object under investigation. It solves this problem by using an extra intensity sensor located at an output for non-dispersed light of the dispersive element used for spectral analysis, e. g. in the zero order ...

    4. Real-time imaging for Spectral Optical Coherence Tomography with massively parallel data processing

      Real-time imaging for Spectral Optical Coherence Tomography with massively parallel data processing
      In this paper the application of massively parallel processing of Spectral Optical Coherence Tomography (SOCT) data with the aid of a low-cost Graphic Processing Unit (GPU) is presented. The reported system may be used for real-time imaging of high resolution 2D tomograms or for presenting volume data. The overall imaging speed is over 100 frames/second for 2D tomograms built of 1024 A-scans and 9 frames/second for 3D volume ...

      Method And Apparatus For Spectral Optical Coherence Tomography (Wo 2009/106358)
      The invention relates to optical coherence tomography (OCT), more specifically to spectral optical coherence tomography (SOCT). The invention deals with the problem of artefacts due to sharp increases of reflection by the object under investigation. It solves this problem by splitting of a part off the returning light for modification of the interferometric data.

    6. Spectral Domain Optical Coherence Tomography as the Profilometric Tool for Examination of the Environmental Influence on Paintings on Canvas

      The changes of surface profile of oil paintings on canvas caused by rapid humidity are examined by spectral OCT. The speed, resolution, and long-time stability of SOCT make this technique appropriate for quantitative determination of surface profile changes.

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

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

    9. Application of graphically oriented programming to imaging of structure deterioration of historic glass by optical coherence tomography

      Application of graphically oriented programming to imaging of structure deterioration of historic glass by optical coherence tomography
      Optical Coherence Tomography (OCT) is an interferometric method utilising light of low temporal coherence for noninvasive structural imaging of objects weakly absorbing and scattering light. In this contribution, using various examples of images of objects made of glass affected by the atmospheric corrosion and/or by crizzling, we demonstrate a software developed in our laboratory specifically for 3D OCT imaging of samples with a fine structure. For this task we ...
