    2. Advanced analysis of domain walls in Mg doped LiNbO3 crystals with high resolution OCT

      Advanced analysis of domain walls in Mg doped LiNbO3 crystals with high resolution OCT
      The structure of domain walls (DW) in ferroelectric media is of great interest as this material is used for frequency doublers and other applications. We show that the structure of the DWs can nicely be visualized by high resolution optical coherence tomography (OCT). While the high group refractive index of lithium niobate allows a resolution much better than 1 m, the large dispersion can blur the image and has to ...

    3. NADPH oxidase 4 protects against development of endothelial dysfunction and atherosclerosis in LDL receptor deficient mice

      NADPH oxidase 4 protects against development of endothelial dysfunction and atherosclerosis in LDL receptor deficient mice
      Aims Endothelial dysfunction is an early step in the development of atherosclerosis. Increased formation of superoxide anions by NADPH oxidase Nox1, 2, and 5 reduces nitric oxide availability and can promote endothelial dysfunction. In contrast, recent evidence supports a vasoprotective role of H 2 O 2 produced by main endothelial isoform Nox4. Therefore, we analysed the impact of genetic deletion of Nox4 on endothelial dysfunction and atherosclerosis in the low-density ...

    6. Characterization of Light Lesion Paradigms and Optical Coherence Tomography as Tools to Study Adult Retina Regeneration in Zebrafish

      Characterization of Light Lesion Paradigms and Optical Coherence Tomography as Tools to Study Adult Retina Regeneration in Zebrafish
      Light-induced lesions are a powerful tool to study the amazing ability of photoreceptors to regenerate in the adult zebrafish retina. However, the specificity of the lesion towards photoreceptors or regional differences within the retina are still incompletely understood. We therefore characterized the process of degeneration and regeneration in an established paradigm, using intense white light from a fluorescence lamp on swimming fish (diffuse light lesion). We also designed a new ...

    8. An advanced algorithm for dispersion encoded full range frequency domain optical coherence tomography

      An advanced algorithm for dispersion encoded full range frequency domain optical coherence tomography
      Dispersion encoded full range (DEFR) optical coherence tomography (OCT) has become highly attractive as it is a simple way to increase the measurement range of OCT systems. Full range OCT is especially favorable as it does not only increase the measurement range but also shifts the highest sensitivity into the center of the measurement range. While the early versions of DEFR were highly computational expensive, new versions reduce the number ...

    9. A hybrid imaging system for simultaneous ophthalmic optical coherence tomography and dual-channel fluorescence detection in small animal models

      A hybrid imaging system for simultaneous ophthalmic optical coherence tomography and dual-channel fluorescence detection in small animal models
      We present a novel hybrid system that allows simultaneous high-resolution spectral domain optical coherence tomography (OCT) in the near-infrared and single-photon excited fluorescence (SPEF) detection in the green and red visible wavelength range for non-invasive multimodal imaging of the retina in small in vivo animal models such as zebrafish.

    10. Feature Of The Week 7/15/12: 3D Simultaneous Optical Coherence Tomography and Confocal Fluorescence Microscopy for Investigation of Lung Tissue

      Feature Of The Week 7/15/12: 3D Simultaneous Optical Coherence Tomography and Confocal Fluorescence Microscopy for Investigation of Lung Tissue
      The acute respiratory distress syndrome (ARDS) is a life-threatening condition of the lung leading to a state of decreased lung compliance and blood oxygenation efficiency. The treatment of patients utilizes artificial ventilation, which has a tremendous impact on the lungs sensitive microenvironment and can even lead to further damage in the form of ventilator induced lung injury (VILI). As a basis for the understanding of physiological processes occurring on the ...

    11. Three-dimensional simultaneous optical coherence tomography and confocal fluorescence microscopy for investigation of lung tissue

      Three-dimensional simultaneous optical coherence tomography and confocal fluorescence microscopy for investigation of lung tissue
      Although several strategies exist for a minimal-invasive treatment of patients with lung failure, the mortality rate of acute respiratory distress syndrome still reaches 30% at minimum. This striking number indicates the necessity of understanding lung dynamics on an alveolar level. To investigate the dynamical behavior on a microscale, we used three-dimensional geometrical and functional imaging to observe tissue parameters including alveolar size and length of embedded elastic fibers during ventilation ...

    12. Endoscopic optical coherence tomography device for forward imaging with broad field of view

      Endoscopic optical coherence tomography device for forward imaging with broad field of view
      One current challenge of studying human tympanic membranes (TM) with optical coherence tomography (OCT) is the implementation of optics that avoid direct contact with the inflamed tissue. At the moment, no commercial device is available. We report an optics design for contactless forward imaging endoscopic optical coherence tomography (EOCT) with a large working distance (WD) and a broad field of view (FOV) by restricting the overall diameter of the probe ...

      Multimodal imaging of lung tissue using optical coherence tomography and two photon microscopy
      In the context of protective artificial ventilation strategies for patients with severe lung diseases, the contribution of ventilator settings to tissue changes on the alveolar level of the lung is still a question under debate. To understand the impact of respiratory settings as well as the dynamic process of respiration, high-resolution monitoring and visualization of the dynamics of lung alveoli are essential. An instrument allowing 3D imaging of lung tissue ...
