Abstract

In the current report, we present a dual-mode approach for assessment of twisted light localization in turbid tissue-like scattering media. A unified open-access Monte Carlo (MC) model based on the tracking of transformations of electric filed vector is working in synergy with 3D geometrical exploration techniques for efficient identification of nonlinear structures produced by twisted light and subsequent tracking of their evolutions in turbid media. We report detection of the light’s twist for up to 6 ODs with <98% confidence intervals/threshold. Results are presented in comparison with exact theoretical solutions and experimental data obtained during laboratory studies. The models are accelerated by parallel programming on graphics cards and offer a responsive online interface.
