Propagation of light carrying orbital angular momentum through a turbid tissue-like scattering medium

We report on the propagation and preservation characteristics of orbital angular momentum (OAM) through turbid tissue-like scattering media. Utilizing both computational simulation and analysis alongside experimental observations, we demonstrate that OAM light preserves phase memory despite propagation through highly scattering environments on a microscopic level (10-6). The study establishes exceptional sensitivity to refractive index variations within the microscopic range and demonstrates a novel approach to phase preservation analysis in complex media. Our findings provide significant implications for biomedical imaging, secure optical communications, and high-precision applications.
