Abstract

In the current report, we present the international efforts to create a unified open-access Monte Carlo (MC) based computational method and a set tools for simulation of Total Angular Momentum (TAM) of light propagating and localizing in turbid tissue-like scattering media. We specifically focus on performing the simulations with a variety of combinations of spin and orbital angular momentum and the subsequent analyses of the spin-orbit interactions. We present an open-access application and a media model which considers both spatial and volumetric variations in the media optical properties. The online application has been accelerated by parallel computations on graphics cards and is being extensively used in the ongoing studies of light's angular momentum propagation in turbid media (e.g. phantoms and cancerous lesions). Rigorous validation against data obtained during experimental studies is presented.
