Abstract
Three Monte Carlo programs were developed which keep track of the status of polarization of light traveling through mono-disperse solutions of micro-spheres. These programs were described in detail in our previous article [1]. This paper illustrates a series of Monte Carlo simulations that model common experiments of light transmission and reflection of scattering media. Furthermore the codes were expanded to model light propagating through poly-disperse solutions of micro-spheres of different radii distributions.
Highlights
Three Monte Carlo programs for polarized light transfer into scattering media have been described and verified in detail [1]
When conducting a standard Monte Carlo program simulation some typical tests are executed, such as total transmission through a slab, or total reflection from a semiinfinite media. This is true for polarized light Monte Carlo programs
We were able to reproduce the Mueller matrix of light backscattered from a solution of micro-spheres obtaining identical patterns to the work published by Cameron et al A skewed illumination-geometry was implemented, both experimentally, and in the simulations
Summary
Three Monte Carlo programs for polarized light transfer into scattering media have been described and verified in detail [1]. When conducting a standard Monte Carlo program simulation some typical tests are executed, such as total transmission through a slab, or total reflection from a semiinfinite media. In addition to the classic numerical test that may be compared with adding doubling simulations, other polarization specific simulations may be conducted One such test is the evaluation of the Mueller matrix backscattered from a solution of micro-spheres. In almost all the previous implementations, as well as ours, the polarization is represented in terms of the Stokes vector For this reason the Monte Carlo programs are unable to simulate coherent phenomena and should be used only in cases where information on the phase is not necessary. Polarized light transfer through a slab of scattering solutions is used as a test for the validity of Monte Carlo programs. The simulations were conducted on a 1.7 GHz Pentium 4 computer, using the Linux Red Hat 7.1 operating system
