    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 ...

    3. Measurements of the thermal coefficient of optical attenuation at different depth regions of in vivo human skins using optical coherence tomography: a pilot study

      Measurements of the thermal coefficient of optical attenuation at different depth regions of in vivo human skins using optical coherence tomography: a pilot study
      We present detailed measurement results of optical attenuations thermal coefficients (referenced to the temperature of the skin surface) in different depth regions of in vivo human forearm skins using optical coherence tomography (OCT). We first design a temperature control module with an integrated optical probe to precisely control the surface temperature of a section of human skin. We propose a method of using the correlation map to identify regions in ...

    4. Polarization scrambling based on cascaded optical polarization devices having modulated optical retardation

      Polarization scrambling based on cascaded optical polarization devices having modulated optical retardation
      Techniques and devices use cascaded optical polarization devices having modulated optical retardation to control optical polarization of light and can be configured for polarization scrambling. Uniform rate scrambling and quasi-uniform rate scrambling modes are provided in described devices and rate-additive designs based on multiple cascaded devices are also disclosed to achieve high-speed scrambling.

    5. Method for improving the resolution and accuracy against birefringence dispersion in distributed polarization cross-talk measurements

      Method for improving the resolution and accuracy against birefringence dispersion in distributed polarization cross-talk measurements
      We present a novel method for improving the spatial resolution and amplitude accuracy of distributed polarization cross-talk measurements in a polarization maintaining (PM) fiber against its birefringence dispersion. We show that the broadening of measured polarization cross-talk peaks caused by birefringence dispersion can be restored by simply multiplying the measurement data with a compensation function. The birefringence dispersion variable in the function can be obtained by finding the widths of ...

    7. Improved fast scanning delay line in optical coherence tomography applications utilizing fiber stretcher

      Lianshan Yan, X. Steve Yao, Lynn Lin et al. We demonstrate an improved fiber-stretcher-based scanning delay line in terms of both the scanning speed and the delay range. Such a module is essential to optical coherence tomography (OCT) applications. An 18-mm delay range at 2-kHz scanning frequency is achieved and verified in a dental OCT setup ... [Opt.
