We present simulation and experimental results showing circular polarization is more tolerant of optical collection geometry (field view area) variations than linear for forward-scattering environments. Circular also persists superiorly in the environment compared to by maintaining its degree better through increasing thicknesses. In contrast, both polarizations are susceptible isotropic-scattering (Rayleigh regime) environments, maintains a small advantage persistence. Simulations measurements presented laboratory-based environments polystyrene microspheres water. Particle diameters were 0.0824 μm (for isotropic-scattering) 1.925 forward-scattering) with an illumination wavelength 543.5 nm.
