摘要

We present a polarization-sensitive version of our PHASR Scanner and a calibration method that allows for accurate measurement of the Stokes vector of the reflected light from sample surfaces. We have tested the performance of the polarimetric scanner by comparing the broadband measurements of the birefringent crystal sapphire to simulations after our Jones matrix calibration approach. The new scanner will enable future polarimetric imaging of biological samples and NDT applications.
