“…This approximation has been confirmed later by various experimental studies [11]. For a medium comprised of a collection of non-absorbing, optically inactive, spatially uncorrelated, spherical particles whose size is much smaller compared to wavelength (radius a λ, anisotropy parameter g ∼ 0, the so-called Rayleigh regime), expression for single path degree of linear and circular polarization (for incident linearly or circularly polarized light respectively) was derived as [11] …”

“…They envisioned that depolarization of light by multiple scattering can be connected to a process of entropy production [10,11]. Based on the so-called maximum entropy principle, it was shown that the single path (photon undergoing successive scattering events) degree of polarization decays exponentially with increasing number of scattering events (n) [10].…”

“…Various approaches using photon diffusion formalisms, random walk models, maximum entropy principles have been used to derive analytical relationships between the degree of polarization (either linear or circular) of forward-scattered or back-scattered light from a turbid medium with the optical transport parameters of the medium [10][11][12][13][14][15]. Such physical modeling is certainly important in gaining physical insight into the mechanism of depolarization of multiply scattered waves in a turbid medium.…”

“…Several studies have therefore been carried out in the recent past to develop experimental strategies for measurement of small polarization-retaining signals in the presence of large depolarized background of multiply scattered light [4,5]. These are supplemented by suitable theoretical treatments (based on radiative transport theory, diffusion theory and Monte Carlo techniques) for modeling polarized light propagation in random medium [10][11][12][13][14][15][16][17]. Numerous studies have also addressed depolarization studies on tissue simulating phantoms (whose constituent scattering and polarization properties are known and user-controlled a priori) to understand the polarization properties of multiply scattered light (and the mechanism of depolarization) in tissue for practical implementation of the polarization gating scheme for tissue imaging [18][19][20][21][22].…”

Abstract. Studies on polarization properties of scattered light from a random medium like biological tissue have received considerable attention because polarization can be used as an effective tool to discriminate against multiply scattered light (acting as a gating mechanism) and thus can facilitate high resolution imaging through tissue. Further, the polarization properties of scattered light from tissue contain wealth of morphological and functional information of potential biomedical importance. However, in a complex random medium like tissue, numerous complexities due to multiple scattering and simultaneous occurrences of many scattering and polarization events present formidable challenges both in terms of accurate measurements and in terms of analysis of the tissue polarimetry signal. Several studies have therefore been conducted in the recent past to develop appropriate measurement procedures, suitable light propagation models and polarimetry signal analysis methods to overcome these difficulties. In this review, we focus on some of the recent key developments in this area. Specifically, we describe variety of theoretical and experimental tools, illustrated with selected results, aimed at evaluating the prospect of turbid medium polarimetry for both biomedical imaging and diagnosis.

We here investigate polarimetric behavior of thick samples of porcine liver, Intralipid, and microsphere-based tissue phantoms whose absorption and scattering properties are matched. Using polarized light we measured reflection mode Mueller matrices and derived linear/circular/total depolarization rates, based on polar decomposition. According to our results, phantoms exhibit greater depolarization rates in the backscattering geometry than the liver sample. The enhanced tissue polarization preservation differs from previous reports of polarimetric transmission studies, with the likely cause of this difference being the angular dependence of the single-scattering phase function. Also, Intralipid approximated polarimetric liver behavior well, whereas the polystyrene phantoms did not.

In this chapter, mathematical and computational light scattering models relevant for halftone reproduction and other simulation studies in digital imaging are discussed. While in principle Maxwell's electromagnetic equations provide a very accurate and general description of light propagation, their numerical solution in highly heterogeneous domains is computationally too expensive for the kind of practical applications considered in this book. Therefore, the focus here will be on the computationally much more efficient transport theory. Besides discussing its limitations, the most general solution approach, that is, the Monte Carlo method, is explained and compared with more simple models, which involve further approximations.
