Abstract
Quantitative imaging of anisotropic dynamics, such as liquid crystal flows, becomes more and more important nowadays . Therefore, there is great demand to develop high-speed quantitative polarization imaging techniques. We propose a novel single-shot, highly accurate and sensitive quantitative polarization imaging technique, called polarized shearing interference microscopy (PSIM), to explore the dynamical properties of disodium cromoglycate (DSCG) under flow at different flow rates. We determine the retardance and orientation angle of DSCG under flow, and show that their spatial and temporal auto-correlation will reduce when the flow rate increases, which is in agreement with the theoretical results based on dimensional analysis of nematic dynamics .
