    2. Optical imaging techniques in microfluidics and their applications

      Optical imaging techniques in microfluidics and their applications
      Microfluidic devices have undergone rapid development in recent years and provide a lab-on-a-chip solution for many biomedical and chemical applications. Optical imaging techniques are essential in microfluidics for observing and extracting information from biological or chemical samples. Traditionally, imaging in microfluidics is achieved by bench-top conventional microscopes or other bulky imaging systems. More recently, many novel compact microscopic techniques have been developed to provide a low-cost and portable solution. In ...

    3. Spectral-Domain Optical Coherence Tomography for Material Detection

      Spectral-Domain Optical Coherence Tomography for Material Detection
      Optical coherence tomography is a non-invasive cross-sectional imaging technology for inhomogeneous samples. Spectral-domain optical coherence tomography is introduced to measure film and Silicon dovetail groove in this paper. A novel method is used to deal with the interference spectrum to improve the quality of the two-dimensional cross-sectional image. The experimental result shows the microstructure of the two samples can be clearly seen as expected. From the visualized two-dimensional cross-sectional imaging ...

    4. Automated Detection of the Foveal Center Improves SD-OCT Measurements of Central Retinal Thickness

      Automated Detection of the Foveal Center Improves SD-OCT Measurements of Central Retinal Thickness
      BACKGROUND AND OBJECTIVE: To investigate the performance of an automated foveal center detection algorithm on spectral-domain optical coherence tomography (SD-OCT). PATIENTS AND METHODS: Fifty normal eyes and 50 eyes with early stage dry age-related macular degeneration (AMD) were analyzed. The actual scan center (SC), automatically detected foveal center (AF), and manually identified foveal center (MF) were compared. RESULTS: The mean of the radial distances was 89 120 m from MF ...

    5. Ex vivo determination of glucose permeability and optical attenuation coefficient in normal and adenomatous human colon tissues using spectral domain optical coherence tomography

      Ex vivo determination of glucose permeability and optical attenuation coefficient in normal and adenomatous human colon tissues using spectral domain optical coherence tomography
      Recent reports have suggested that spectral domain optical coherence tomography (SD-OCT) is a useful tool for quantifying the permeability of hyperosmotic agents in various tissues. We report our preliminary results on quantification of glucose diffusion and assessment of the optical attenuation change due to the diffusion of glucose in normal and adenomatous human colon tissues in vitro by using a SD-OCT and then calculated the permeability coefficients (PC) and optical ...

    6. Normal corneal thickness measurements in pigmented rabbits using spectral-domain anterior segment optical coherence tomography

      Normal corneal thickness measurements in pigmented rabbits using spectral-domain anterior segment optical coherence tomography
      Objective To document the thickness of the central cornea in pigmented rabbits using spectral-domain anterior segment optical coherence tomography (AS-OCT). Animals studied Seventeen pigmented rabbits (6 male, 11 female, both eyes) were involved in this study. Procedures Thirty-four eyes from healthy pigmented rabbits underwent a complete ophthalmologic examination, including AS-OCT. Eight radial scans, 6 mm in length and centered on the cornea, were obtained using the AS-OCT. Corneal thickness was ...

    8. Optical coherence tomography for whole eye segment imaging

      Optical coherence tomography for whole eye segment imaging
      We proposed a dual focus dual channel spectral domain optical coherence tomography (SD-OCT) for simultaneous imaging of the whole eye segments from cornea to the retina. By using dual channels the system solved the problem of limited imaging depth of SD-OCT. By using dual focus the system solved the problem of simultaneous light focusing on the anterior segment of the eye and the retina. Dual focusing was achieved by adjusting ...

    9. High resolution spectral-domain optical coherence tomography using a thermal light source

      High resolution spectral-domain optical coherence tomography using a thermal light source
      Abstract A high resolution spectral-domain optical coherence tomography (SD-OCT) system based on a thermal light source was presented. A novel normalized method was introduced to remove the background noise and the DC noise of the interference spectrum. A Gaussian spectral calibration procedure was performed to improve axial resolution and image quality before reconstructing OCT image. With the proposed method, the quality of the obtained images was greatly improved. Two-dimensional (2D ...

    10. In-vivo full depth of eye imaging spectral domain optical coherence tomography

      In-vivo full depth of eye imaging spectral domain optical coherence tomography
      It is necessary to apply the spectral-domain optical coherence tomography (SD-OCT) to image the whole eye segment for practically iatrical application, but the imaging depth of SD-OCT is limited by the spectral resolution of the spectrometer. By now, no result about this research has been reported. In our study, a new dual channel dual focus OCT system is adopted to image the whole eye segment. The cornea and the crystalline ...
