Elaboration of strategies for polarization-sensitive ultrahigh resolution visible light optical coherence tomography
On demand | Presented live 26 January 2025 
Abstract
An ultra-high resolution visible light (VIS-)OCT system has been assembled and was used to examine human oral mucosa. With an illumination band of 540 to 930nm, the system is characterized with maximal measurement depth of zmax = 1.34mm, while the axial resolution was determined to Δz = (1.4 ± 0.2) µm. The extension of the VIS-OCT system to a polarization sensitive setup with two single linear input states is discussed, whereat for each input state co- and cross-polarization are measured. Three possibilities are presented.

Johannes Reinhold, M.Sc. (*1998) studied Physics at the University of Rostock, specialising in "Nanotechnologies and New Materials," and received an overall grade of "good" for his degree (M.Sc.). His master's thesis, titled "Photoluminescence Spectroscopy on Transition Metal Dichalcogenides and 2D van der Waals Heterostructures," along with its defence, were completed with the highest distinction (1.0). Following his studies, Mr Reinhold began working as a research associate in the "Medical Physics and Biomedical Engineering" department under the supervision of Dr. rer. medic. habil. Julia Walther at the University Hospital Carl Gustav Carus in Dresden in October 2023. As a young scientist, Mr Reinhold focuses particularly on high-resolution VIS-OCT systems.
