    2. Corneal, Limbal, and Conjunctival Epithelial Thickness from Optical Coherence Tomography.

      Purpose. To compare human central corneal, limbal and bulbar conjunctival epithelial thickness in vivo using an Optical Coherence Tomographer (OCT). Methods. Thirteen healthy human subjects participated in this study. An OCT (Carl Zeiss, Meditec, Dublin, CA) was used to image central cornea, temporal corneo-scleral limbus and bulbar conjunctiva of the left eye. Two images were taken at each location. Thirty central measurements were averaged from each image for quantifying epithelial ...

    3. Finite difference time-domain model of light scattering from retinal photoreceptors

      Samer Abdallah, Alex Iolov, Omar M. Ramahi et al. Functional ultra high resolution optical coherence tomography (fUHROCT) was used to non-invasively probe the functional response of retinal photoreceptors. Using this technique, time dependent changes in light reflectivity of the retinal photoreceptor layer were measured after external white light s ... [Proc. SPIE Int. Soc. Opt.

    4. Submicrometer axial resolution optical coherence tomography.

      Optical coherence tomography (OCT) with unprecedented submicrometer axial resolution achieved by use of a photonic crystal fiber in combination with a compact sub-10-fs Ti:sapphire laser (Femtolasers Produktions) is demonstrated for what the authors believe is the first time. The emission spectrum ranges from 550 to 950 nm (lambda(c)=725 nm , P(out)=27 mW) , resulting in a free-space axial OCT resolution of ~0.75 mum , corresponding to ~0 ...

    5. Speckle noise reduction algorithm for optical coherence tomography based on interval type II fuzzy set

      Prabakar Puvanathasan, Kostadinka Bizheva. A novel speckle reduction technique based on soft thresholding of wavelet coefficients using interval type II fuzzy system was developed for reducing speckle noise in Optical Coherence Tomography images. The proposed algorithm is an extension of a recently published method for filtering additive ... [Opt. Express 15, 15747-15758 (2007)]
