Viscoelastic modului, |G*(ω)|, extracted from g2(t) curves of Fig. 2, using (a) DWS equation, and (b) PSCT-MCRT based approach. The viscoelastic modulus measured using a conventional rheometer is shown as a black dashed curve. For these primarily scattering samples of negligible absorption, DWS fails to yield an accurate estimate of viscoelastic properties. In contrast, PSCT-MCRT successfully derives the moduli from g2(t) curves of Fig. 2.
