Abstract
We show that light transport in a turbid medium can be described by a path integral with a quasi-particle Lagrangian. The most probable trajectory over which photons can be found can be obtained from this Lagrangian. This approach extends the diffusion approximation to the near-diffusive regime, in which photons travel only a few transport mean free paths.
