Abstract

Polarization modulation technique has been applied for magneto-optical (MO) imaging to measure MO values quantitatively. In this paper, we report on a real-time MO imaging using the polarization modulation method with a liquid crystal modulator. Measurements of MO images and hysteresis Kerr loop of patterned Bi,Ga substituted yttrium iron garnet film were demonstrated by using the technique. A frame rate of 1 s was achieved in this experiment.
