    3. Qualitative investigation of fresh human scalp hair with full-field optical coherence tomography

      Qualitative investigation of fresh human scalp hair with full-field optical coherence tomography
      We have investigated depth-resolved cellular structures of unmodified fresh human scalp hairs with ultrahigh-resolution full-field optical coherence tomography (FF-OCT). The Linnik-type white light interference microscope has been home-implemented to observe the micro-internal layers of human hairs in their natural environment. In hair shafts, FF-OCT has qualitatively revealed the cellular hair compartments of cuticle and cortex layers involved in keratin filaments and melanin granules. No significant difference between black and white ...

    8. Feasibility of Full-field Optical Coherence Microscopy in Ultra-structural Imaging of Human Colon Tissues

      Feasibility of Full-field Optical Coherence Microscopy in Ultra-structural Imaging of Human Colon Tissues
      We demonstrated imaging feasibility of full-field optical coherence microscopy (FF-OCM) in pathological diagnosis of human colon tissues. FF-OCM images enabling high transverse resolution were obtained at different depth of the samples without any dye staining and physical slicing and visualized detailed microstructure of the human colon tissues. Morphological differences in normal tissues, cancer tissues and tissues under transition state were observed and matched with results seen in conventional optical microscope ...

    12. All-fiber probe for optical coherence tomography

      Seon Young Ryu, Hae Young Choi, Jihoon Na et al. We propose an all-fiber probe for the sample arm of an optical coherence tomography (OCT) system. By forming a focusing lens directly on the tip of an optical fiber, a compact sample probe could be implemented. To achieve a long enough working distance and a high enough lateral resolution at the sam ... [Proc. SPIE Int. Soc. Opt. Eng. 6847, 68472L ...
