$1 GPU simulation results with the same parameters as in Fig. 4 of [9]. Thickness of the medium is 1 cm, refractive index n=1.33, wavelength of light is 633 nm. Radius, refractive index, and scattering coefficient of the spherical scatterer in the simulations in (a) and (b) are rs=0.1 μm, ns=1.59, μs=10 cm−1, and in the sphere–cylinder mixed simulations in (c) and (d), μs=5 cm−1. For the cylindrical scatterer in the simulations in (c) and (d), rc=0.75 μm, nc=1.56, μc(90°)=65 cm−1. The direction of the cylinders is along the y axis, and the standard deviation for the Gauss distribution of the direction is 5°. The birefringence value in the simulations in (b) and (d) is 1×10−5, corresponding to an extension of 5 mm. The birefringence axis is along the 45° direction on the x–y plane. The cutoff numbers of scattering steps are all set to 200. The number of simulated photons is 1.2×108 for each group. The detector area is 1 cm×1 cm, partitioned into 100×100 pixels.$ Source: Pengcheng Li, Celong Liu, Xianpeng Li, Honghui He, Hui Ma, "GPU acceleration of Monte Carlo simulations for polarized photon scattering in anisotropic turbid media," Appl.
