    2. Rapid measurement of transversal flow velocity vector with high spatial resolution using speckle decorrelation optical coherence tomography

      Rapid measurement of transversal flow velocity vector with high spatial resolution using speckle decorrelation optical coherence tomography
      We propose and demonstrate a novel method that uses only three sets of B-scans to accurately determine both the direction and the speed of a transversal flow using speckle decorrelation optical coherence tomography. Our tri-scan method has the advantages of high measurement speed, high spatial resolution, and insensitivity to the flow speed. By introducing error maps, we show that the flow angle inaccuracy can be minimized by choosing the measurement ...

    4. Adaptive Speckle Reduction in OCT Volume Data Based on Block-Matching and 3-D Filtering

      Adaptive Speckle Reduction in OCT Volume Data Based on Block-Matching and 3-D Filtering
      An adaptive speckle denoising method called Volume-BM3D is developed for optical coherence tomography (OCT) volume data processing, including an adaptive noise level estimation algorithm and a denoising strategy based on block-matching and filtering in a highly sparse local 3-D transform domain. Noise level estimation, an important step for denoising, is obtained from estimating signal fluctuations among neighboring A-Scans. Unlike 2-D denoising approaches, the Volume-BM3D considers the similarities of tissue structures ...

    5. Measurement of the refractive index of human teeth by optical coherence tomography

      We describe a novel method based on optical coherence tomography (OCT) for the accurate measurement of the refractive index of in vitro human teeth. We obtain the refractive indices of enamel, dentin, and cementum to be 1.6310.007, 1.5400.013, and 1.5820.010, respectively. The profile of the refractive index is readily obtained via an OCT B scan across a tooth. This method can be used to ...
