    1. Static and dynamic crystalline lens accommodation evaluated using quantitative 3-D OCT

      Static and dynamic crystalline lens accommodation evaluated using quantitative 3-D OCT
      Custom high-resolution high-speed anterior segment spectral domain Optical Coherence Tomography (OCT) provided with automatic quantification and distortion correction algorithms was used to characterize three-dimensionally (3-D) the human crystalline lens in vivo in four subjects, for accommodative demands between 0 to 6 D in 1 D steps. Anterior and posterior lens radii of curvature decreased with accommodative demand at rates of 0.73 and 0.20 mm/D, resulting in an ...

    2. Corneal topography with high-speed swept source OCT in clinical examination

      Corneal topography with high-speed swept source OCT in clinical examination
      We present the applicability of high-speed swept source (SS) optical coherence tomography (OCT) for quantitative evaluation of the corneal topography. A high-speed OCT device of 108,000 lines/s permits dense 3D imaging of the anterior segment within a time period of less than one fourth of second, minimizing the influence of motion artifacts on final images and topographic analysis. The swept laser performance was specially adapted to meet imaging ...

    4. 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 ...

    5. Ultra high-speed swept source OCT imaging of the anterior segment of human eye at 200 kHz with adjustable imaging range

      Ultra high-speed swept source OCT imaging of the anterior segment of human eye at 200 kHz with adjustable imaging range
      We present an application of in vivo anterior segment imaging of the human eye with an ultrahigh speed swept source OCT instrument. For this purpose, a dedicated OCT system was designed and constructed. This instrument enables axial zooming by automatic reconfiguration of spectral sweep range; an enhanced imaging range mode enables imaging of the entire anterior segment while a high axial resolution mode provides detailed morphological information of the chamber ...

    6. Anterior segment imaging with Spectral OCT system using a high-speed CMOS camera

      Anterior segment imaging with Spectral OCT system using a high-speed CMOS camera
      We describe a new ultrahigh speed Spectral OCT instrument making use of a CMOS camera and demonstrate high quality in vivo imaging of the anterior segment of the human eye. The high flexibility of the designed imaging system allows a wide range of imaging protocols. Two- and three-dimensional high ... [Opt. Express 17, 4842-4858 (2009)]

    7. Comparison of reflectivity maps and outer retinal topography in retinal disease by 3-D Fourier domain optical coherence tomography

      Comparison of reflectivity maps and outer retinal topography in retinal disease by 3-D Fourier domain optical coherence tomography
      We demonstrate and compare two image processing methods for visualization and analysis of three-dimensional optical coherence tomography (OCT) data acquired in eyes with different retinal pathologies. A method of retinal layer segmentation based on a multiple intensity thresholding algorithm was ... [Opt. Express 17, 4189-4207 (2009)]

    8. Segmentation of flowing particles using joint spectral and time domain optical coherence tomography

      We propose a modified method of acquisition and analysis of Spectral Optical Coherence Tomography (SOCT) data to provide information about flow velocities in three dimensions. Joint Spectral and Time domain Optical Coherence Tomography (joint STdOCT) enables flow velocity assessment and segmentation ... [Proc. SPIE 7168, 71680C (2009)] published Thu Feb 19, 2009.

      Karol Karnowski, Michalina Gora, Bartlomiej Kaluzny et al. We present applicability of the high speed swept-source optical coherence tomography for in vivo imaging of the anterior segment of the human eye. Three dimensional imaging of the cornea with reduced motion artifacts is possible by using swept source with Fourier domain mode locking operating at 200 ... [Proc. SPIE 7163, 716308 (2009)] published Wed Feb 18, 2009.

    10. Optical Coherence Tomography for Tracking Canvas Deformation

      Optical Coherence Tomography for Tracking Canvas Deformation
      Preliminary results of the application of optical coherence tomography (OCT), in particular in its spectral mode (SOCT), to tracking of deformations in paintings on canvas caused by periodical humidity changes are presented. The setup is able to monitor the position of a chosen point at the surface of a painting with micrometre precision, simultaneously in three dimensions, every 100 seconds. This allows recording of deformations associated with crack formation. For ...
