    2. In Vivo Rat Brain Imaging through Full-Field Optical Coherence Microscopy Using an Ultrathin Short Multimode Fiber Probe

      In Vivo Rat Brain Imaging through Full-Field Optical Coherence Microscopy Using an Ultrathin Short Multimode Fiber Probe
      We demonstrate full-field optical coherence microscopy (OCM) using an ultrathin forward-imaging short multimode fiber (SMMF) probe with a core diameter of 50 m, outer diameter of 125 m, and length of 7.4 mm, which is a typical graded-index multimode fiber used for optical communications. The axial and lateral resolutions were measured to be 2.14 m and 2.3 m, respectively. By inserting the SMMF 4 mm into the ...

    3. Rat brain imaging using full field optical coherence microscopy with short multimode fiber probe

      Rat brain imaging using full field optical coherence microscopy with short multimode fiber probe
      We demonstrated FF OCM(full field optical coherence microscopy) using an ultrathin forward-imaging SMMF (short multimode fiber) probe of 50 m core diameter, 125 m diameter, and 7.4 mm length, which is a typical graded-index multimode fiber for optical communications. The axial resolution was measured to be 2.20 m, which is close to the calculated axial resolution of 2.06 m. The lateral resolution was evaluated to be ...

    4. Ultrathin forward-imaging short multimode fiber probe for full-field optical coherence microscopy

      Ultrathin forward-imaging short multimode fiber probe for full-field optical coherence microscopy
      To extend the applications of optical coherence tomography (OCT) to the fields of physiology and clinical medicine, less invasive, robust, and reliable optical probes are required. Thus, we demonstrate an ultrathin forward-imaging short multimode fiber (SMMF) optical coherence microscopy (OCM) probe with a 50 m core diameter, 125 m total diameter, and 5.12 mm length. Imaging conditions and magnification were analyzed, and they correspond closely to the measured results ...

    5. Reflection, phase and en -face sectional imaging of scattering objects using quasi-single-shot wide-field optical coherence tomography

      Reflection, phase and en -face sectional imaging of scattering objects using quasi-single-shot wide-field optical coherence tomography
      We report a quasi-single-shot wide-field optical coherence tomography system that enables to measure the reflection, phase and en - face OCT images from the same setup using the glass jig. The jig consisting of a wedge glass substrate and a glue dot is contacted to the tissue surfaces, and the data within glue dot is used to reduce the phase noise of the interference signal. The reconstructed image size of the ...

    6. Improvement of the dynamic range using background subtraction in single shot wide-field optical coherence tomography

      Improvement of the dynamic range using background subtraction in single shot wide-field optical coherence tomography
      We investigated on the signal in single shot wide-field optical coherence tomographic (SS-WF-OCT) system to improve the dynamic range (DR). The SS-WF-OCT system is based on two-dimensional (2D) polarization Michelson interferometer and superluminescent diode (center wavelength of 842.5nm) as light source. Two-phase-shifted interferograms were acquired simultaneously using a single CCD camera and after subtraction, theen-faceOCT image (area (x) 4.0mm(y) 4.3mm) is obtained using 2D Hilbert transform ...

    7. Application of Wide-Field Optical Coherence Tomography to Monitoring of Viability of Rat Brain In Vivo

      Application of Wide-Field Optical Coherence Tomography to Monitoring of Viability of Rat Brain In Vivo
      We investigated the feasibility of OCT in monitoring the viability of the brain. It was confirmed that after an overdose of pentobarbital sodium salt for an euthanasia, the OCT signal intensity increased before cardiac arrest and finally became 2.7 times, and by periodically changing the tissue temperature from 20 to 32 ℃ in vivo, average correlation coefficients between the ratio of signal intensity (RSI) and temperature were determined to be ...
