MO imaging using a magneto-optical (MO) imaging plate is a magnetic imaging technique that can visualize magnetic field distribution in real time. We have proposed MO imaging by circular polarization modulation methods and color imaging methods as a method to quantitatively measure the magnetic field distribution. In this paper, we report on a measurement method using a polarization camera that enables quantitative measurement in a single shot.
