    2. Dynamic full field optical coherence tomography: subcellular metabolic contrast revealed in tissues by interferometric signals temporal analysis

      Dynamic full field optical coherence tomography: subcellular metabolic contrast revealed in tissues by interferometric signals temporal analysis
      We developed a new endogenous approach to reveal subcellular metabolic contrast in fresh ex vivo tissues taking advantage of the time dependence of the full field optical coherence tomography interferometric signals. This method reveals signals linked with local activity of the endogenous scattering elements which can reveal cells where other OCT-based techniques fail or need exogenous contrast agents. We benefit from the micrometric transverse resolution of full field OCT to ...

    3. High-resolution handheld rigid endomicroscope based on full-field optical coherence tomography

      High-resolution handheld rigid endomicroscope based on full-field optical coherence tomography
      Full-field optical coherence tomography (FF-OCT) is a powerful tool for nondestructive assessment of biological tissue, i.e., for the structural examination of tissue in depth at a cellular resolution. Mostly known as a microscopy device for ex vivo analysis, FF-OCT has also been adapted to endoscopy setups since it shows good potential for in situ cancer diagnosis and biopsy guidance. Nevertheless, all the attempts to perform endoscopic FF-OCT imaging did ...

    7. Method and device for high resolution full field interference microscopy

      Method and device for high resolution full field interference microscopy
      The invention relates to an incoherent light full field interference microscopy device for the imaging of a volumetric scattering sample (106). The device comprises an interference device (100) between a reference wave (401), produced by reflection of an incident wave by a reflective surface (105) of a reference arm of the interference device, and an object wave (402) produced by backscattering of the incident wave by a slice of the ...

    8. Full-Field Optical Coherence Tomography of Human Donor and Pathological Corneas

      Full-Field Optical Coherence Tomography of Human Donor and Pathological Corneas
      Purpose : To evaluate the performance of a full-field optical coherence tomography (FF-OCT) system in the study of human donor and pathological corneas and assess its suitability for use in eye banks. Methods : Our study was carried out using an FF-OCT system developed for non-invasive imaging of tissue structures in depth with ultrahigh resolution (1m in all directions). Images were acquired from eight stored human donor corneas (either edematous or after ...

    9. High resolution in-vivo imaging of skin with full field optical coherence tomography

      High resolution in-vivo imaging of skin with full field optical coherence tomography
      Full-field OCT (FFOCT) has the ability to provide en-face images with a very good axial sectioning as well as a very high transverse resolution (about 1 microns in all directions). Therefore it offers the possibility to visualize biological tissues with very high resolution both on the axial native view, and on vertical reconstructed sections. Here we investigated the potential dermatological applications of in-vivo skin imaging with FFOCT. A commercial FFOCT ...

    10. Feature Of The Week 6/9/13: Imaging of Non-Tumorous and Tumorous Human Brain Tissues with Full-Field OCT

      Feature Of The Week 6/9/13: Imaging of Non-Tumorous and Tumorous Human Brain Tissues with Full-Field OCT
      A prospective study was performed on neurosurgical samples from 18 patients to evaluate the use of full-field optical coherence tomography (FF-OCT) in brain tumor diagnosis. FF-OCT captures en face slices of tissue samples at 1 m resolution in 3D to a penetration depth of around 200 m. A 1 cm2 specimen is scanned at a single depth and processed in about 5 min. This rapid imaging process is non-invasive and ...
