Engineering Illuminatio n Through Multimode Fibers for Imaging and Metrology
Multimode fibers support the propagation of hundreds or thousands of optical m odes, resulting in complex interference and highly scrambled output f ields. While such complexity has traditionally been considered a limi tation for imaging and precise light delivery, recent advances in pho tonics and computational optics have transformed multimode fibers int o controllable optical systems for engineered illumination. In this t hesis, the potential of multimode fibers as flexible tools for illumi nation control in imaging and optical metrology is explored. The cent ral idea of this work is that illumination should not be treated as a fixed property of an optical system, but rather as a parameter that can be manipulated and designed depending on the application. In this study, several key challenges related to illumination engineering th rough multimode fibers are addressed. The work investigates how compl ex light propagation through multimode fibers can be controlled and e xploited for imaging, computational reconstruction, and phase retriev al. Different approaches for generating, manipulating, and utilizing complex illumination fields are explored, demonstrating the potential of multimode fibers not only as passive waveguides, but also as acti ve optical elements for advanced imaging and metrology applications.< /p>

DESCRIPTION: Multimode fibers support the propagation of hundreds or t housands of optical modes, resulting in complex interference and high ly scrambled output fields. While such complexity has traditionally b een considered a limitation for imaging and precise light delivery, r ecent advances in photonics and computational optics have transformed multimode fibers into controllable optical systems for engineered il lumination. In this thesis, the potential of multimode fibers as flex ible tools for illumination control in imaging and optical metrology is explored. The central idea of this work is that illumination shoul d not be treated as a fixed property of an optical system, but rather as a parameter that can be manipulated and designed depending on the application. In this study, several key challenges related to illumi nation engineering through multimode fibers are addressed. The work i nvestigates how complex light propagation through multimode fibers ca n be controlled and exploited for imaging, computational reconstructi on, and phase retrieval. Different approaches for generating, manipul ating, and utilizing complex illumination fields are explored, demons trating the potential of multimode fibers not only as passive wavegui des, but also as active optical elements for advanced imaging and met rology applications.
