Fiber Optics, From Sensing to Non Invasive High Resolution Medical Imaging

A review is presented on a selection of methods and devices initially developed by the fiber optic, sensing and fiber laser communities which have later found applications in high resolution non-invasive optical imaging. Three avenues have been identified in the modern low coherence interferometry and in the optical coherence tomography technologies which have taken inspiration from fiber optic sensing, fiber optic devices, fiber lasers and fiber optic communications: 1) optical sources; 2) optical configurations; and 3) signal processing. The review will illustrate state of the art examples of concept evolution along these three avenues.
