directly within the complexity of living organisms. However, majority of practical techniques
used nowadays for tissue visualization can only reach depths of a few tens of micrometres as
the issue obscures deep imaging due to the random light scattering. Several imaging
techniques deal with this problems from different angels, such as optical coherence
tomography, light sheet microscopy or structured light illumination A different and promising strategy to overcome the turbid nature of scattering tissues is to employ multimode optical fibers (MMF) as minimally invasive light guides or endoscopes to provide optical access inside. Although the theoretical description of light propagation through such fibers has been developed a long time ago it is frequently considered inadequate to describe real MMF. The inherent randomization of light propagating through MMFs is typically attributed to undetectable deviations from the ideal fiber structure. It is a commonly believed that this
additional chaos is unpredictable and that its influence grows with the length of the fiber.
Despite this, light transport through MMFs remains deterministic and can be characterized by a transmission matrix (TM) which connects the intensity and phase patterns on the fiber input and output facets. Once the TM is known it can be used to create focus in any desired 3D
coordinates beyond the distal fiber facet, see figure 1, and perform e.g. fluorescence based
laser scanning microscopy or optical trapping.Pracoviště Ústav přístrojové techniky Kontakt Martina Šillerová, sillerova@ISIBrno.Cz, Tel.: 541 514 178 Rok sběru 2019
