“…3. The PS-ISAM images for both the birefringent phantom and human tissue samples showed improvement over the PS-OCT images in the anisotropy 7,15 and Sobel 16 image metrics of greater than 50% and 7.5%, respectively. This improved image quality could potentially benefit the detection of residual cancer in breast tumor margins, where the polarization information can aid in the differentiation between normal and diseased tissue by identifying birefringent regions as collagenous stroma.…”

“…The valid polarization information is localized to areas with sufficient signal corresponding to the scattering particles in the intensity images, which have phase retardation values near the extremes of the scale corresponding to right-and left-handed polarization states. 15 Comparison of the PS-OCT and PS-ISAM images reveals improved localization of the phase retardation information in the PS-ISAM reconstruction due to the improved transverse resolution. The traces for a single particle shown in Figs. 2(e) and 2(f) highlight the improvement of the ISAM and PS-ISAM reconstruction over the standard techniques.…”

Three-dimensional optical microscopy suffers from the well-known compromise between transverse resolution and depth-of-field. This is true for both structural imaging methods and their functional extensions. Interferometric synthetic aperture microscopy (ISAM) is a solution to the 3D coherent microscopy inverse problem that provides depth-independent transverse resolution. We demonstrate the extension of ISAM to polarization sensitive imaging, termed polarization-sensitive interferometric synthetic aperture microscopy (PS-ISAM). This technique is the first functionalization of the ISAM method and provides improved depth-of-field for polarization-sensitive imaging. The basic assumptions of polarization-sensitive imaging are explored, and refocusing of birefringent structures is experimentally demonstrated. PS-ISAM enables high-resolution volumetric imaging of birefringent materials and tissue.

“…We adapted the Jones-based formalism to handle linear or circular polarization of coherent light traveling through a random turbid medium. 33 The developed MC approach is a part of the O3MC online tool 20,21 and has been extended for modelling propagation and scattering of vector light beams in complex tissue-like scattering media.…”

Due to its high sensitivity to subtle alterations in medium morphology the vector light beams have recently gained much attention in the area of photonics. This leads to development of a new non-invasive optical technique for tissue diagnostics. Conceptual design of the particular experimental systems requires careful selection of various technical parameters, including beam structure, polarization, coherence, wavelength of incident optical radiation, as well as an estimation of how the spatial and temporal structural alterations in biological tissues can be distinguished by variations of these parameters. Therefore, an accurate realistic description of vector light beams propagation within tissue-like media is required. To simulate and mimic the propagation of vector light beams within the turbid scattering media the stochastic Monte Carlo (MC) technique has been used. In current report we present the developed MC model and the results of simulation of different vector light beams propagation in turbid tissue-like scattering media. The developed MC model takes into account the coherent properties of light, the influence of reflection and refraction at the medium boundary, helicity flip of vortexes and their mutual interference. Finally, similar to the concept of higher order Poincaré sphere (HOPS), to link the spatial distribution of the intensity of the backscattered vector light beam and its state of polarization on the medium surface we introduced the color-coded HOPS.

“…Definitely, this requires a larger statistical sample and, in addition, defining some sort of discrete ordinates, which can be numerically problematic. However, if the separation between the source and the detector r ab is sufficiently large, the integration in (13) takes place in the spatial regions where the angular dependence of at least one of the Green's functions involved is relatively weak. We therefore can adopt the following approach to computing the angular dependence of the Green's function.…”

“…Backscattering imaging geometry and illustration of various geometrical objects that are relevant to the reciprocity principle that is considered in this Letter.vRTE is presently not available. Instead, the contemporary mainstream approach to solving vRTE is to use Monte Carlo (MC) simulations [12,13]. However, application of MC simulation to computing the sensitivity function can be so time-consuming as to render the approach impractical.…”

Reciprocity relation for the vector radiative transport equation and its application to diffuse optical tomography with polarized light

et al. 2017

We derive a reciprocity relation for the 3D vector radiative transport equation that describes propagation of polarized light in multiple-scattering media. We then show how this result, together with translational invariance of a plane-parallel sample, can be used to efficiently compute the sensitivity kernel of diffuse optical tomography by Monte Carlo simulations. Numerical examples of polarization-selective sensitivity kernels are given.
