[EN] FBG in polymer optical fibers (POFs) is a promising technology for a wide range of sensing applications due to a lower Young¿s modulus and a large range of applying strain. Furthermore, POFs have several properties ...
[EN] Optical coherence tomography (OCT) is a well-established bedside imaging modality that allows analysis of skin structures in a non-invasive way. Automated OCT analysis of skin layers is of great relevance to study ...
