      In vivo characterisation of healthy human skin with a novel, non‐invasive imaging technique: line‐field confocal optical coherence tomography

      Background Line‐field confocal optical coherence tomography (LC‐OCT) is a non‐invasive optical technique recently developed for skin examination in vivo . It provides real‐time, high‐resolution vertical images with an isotropic resolution of ~1 µm and a penetration depth of ~500 µm. Objectives Study goals were to qualitatively/quantitatively characterise healthy skin at different body sites using LC‐OCT. Methods The skin of young healthy volunteers was imaged with a handheld LC‐OCT imaging device. Seven body sites (back of the hand, forehead, cheek, nose, chest, forearm, and back) were investigated. An independent qualitative [cutaneous structures’ description; visibility ...

    2. Color high resolution full-field optical coherence microscopy for contrast-enhanced imaging

      Color high resolution full-field optical coherence microscopy for contrast-enhanced imaging

      Full-field optical coherence microscopy (FF-OCM) is an established optical technology based on low-coherence interference microscopy for high-resolution non-invasive three-dimensional imaging of semi-transparent samples. We present an extension of the technique setting up an achromatic imaging system over a spectral range extending from 530 nm to 1700 nm, to provide tomographic images in three distinct bands centered at 635 nm, 870 nm and 1170 nm. Image contrast enhancement as well as sample characterization is performed using the conventional RGB color channel representation. Light is emitted by a halogen lamp and then separates into two arms of a Linnik-type interferometer with microscope ...

    3. Full-field optical coherence tomography (oct) and early alterations in chloroplast morphology

      Full-field optical coherence tomography (oct) and early alterations in chloroplast morphology
      A. C. Boccara, R. De Paepe, A. Dubois et al. After our first demonstration of the early alteration of the chloroplast morphology with the use of both Confocal Microscopy and Optical Coherence Tomography (OCT) and the discussion of the biological mechanisms, we develop here the optical part of this work and underline the merits of full field OC ...
