Polarization light microscopes are powerful tools for probing molecular orderand orientation in birefringent materials. While a multitude of polarizationlight microscopy techniques are often used to access steady-state properties ofbirefringent samples, quantitative measurements of the molecular orientationdynamics on the millisecond time scale have remained a challenge. We proposepolarized shearing interference microscopy (PSIM), a single-shot quantitativepolarization imaging method, for extracting the retardance and orientationangle of the laser beam transmitting through optically anisotropic specimenswith complex structures. The measurement accuracy and imaging performances ofPSIM are validated by imaging a rotating wave plate and a bovine tendonspecimen. We demonstrate that PSIM can quantify the dynamics of a flowinglyotropic chromonic liquid crystal in a microfluidic channel at an imagingspeed of 506 frames per second (only limited by the camera frame rate), with afield-of-view of up to $350\times350 \mu m^2$ and a diffraction-limit spatialresolution of $\sim 2\mu m$. We envision that PSIM will find a broad range ofapplications in quantitative material characterization under dynamicalconditions.
