    1. Human Skin as Arrays of Helical Antennas in the Millimeter and Submillimeter Wave Range

      Author(s): Yuri Feldman, Alexander Puzenko, Paul Ben Ishai, Andreas Caduff, and Aharon J. AgranatRecent studies of the minute morphology of the skin by optical coherence tomography showed that the sweat ducts in human skin are helically shaped tubes, filled with a conductive aqueous solution. A computer simulation study of these structures in millimeter and submillimeter wave bands show that th...[Phys. Rev. Lett. 100, 128102] Published Thu Mar 27, 2008

    2. Quantitative analysis on tongue inspection in traditional Chinese medicine using optical coherence tomography

      Tongue inspection (TI) is an important and unique diagnostic method in traditional Chinese medicine (TCM), because significant connections between various viscerae diseases and abnormalities in the tongue have been verified. In TCM, TI is simple and non invasive, but in clinical applications, TI is subjectively based on the experience and technique of physicians. To avoid this problem, optical coherence tomography (OCT) imaging is introduced here for TI. We study OCT imaging in rats in vivo from chronic gastritis group (model) and normal group (control) and quantitatively analyze the relative parameters, such as the thickness and the moisture degree of TI ...

    3. Mid-infrared optical coherence tomography

      Christopher S. Colley, Jeremy C. Hebden, David T. Delpy, Alison D. Cambrey, Robert A. Brown et al. A time domain optical coherence tomography (OCT) system is described that uses mid-infrared light (68 [mu]m). To the best of our knowledge, this is the first OCT system that operates in the mid-infrared spectral region. It has been designed to characterize bioengineered tissues in terms of their st ... [Rev.

    4. Common-path optical coherence tomography with side-viewing bare fiber probe for endoscopic optical coherence tomography

      Common-path optical coherence tomography with side-viewing bare fiber probe for endoscopic optical coherence tomography
      All-fiber-optic common-path optical coherence tomography (OCT) using a side-viewing bare fiber probe has been demonstrated and analyzed. A bare single mode fiber tip is angle cleaved at ∼ 49° to enable side illumination due to total internal reflection. The bare fiber probe was inserted in an arterial tissue and a circumferential OCT scan was obtained. The research is aimed at realizing highly miniaturized monolithic probes for possible applications in miniature endoscopic OCT or intravascular OCT. The effects of the angle of the cleaved fiber on reference reflection and the sensitivity of the common-path OCT system have been studied theoretically. The angle ...

    6. Optical coherence computed tomography

      Li Li and Lihong V. Wang Optical Imaging Laboratory, Department of Biomedical Engineering, Washington University in St. Louis, St. Louis, Missouri 63130, USA A time-resolved optical tomography, optical coherence computed tomography, is proposed to bridge the gap between diffuse optical tomography and optical coherence tomography. Both ballistic and multiple-scattered photons are measured at multiple source-detection positions by low-coherence interferometry providing a temporal resolution smalle
