Abstract
In measuring a change in the polarization state of light attributed to magnetooptic anisotropy, a means for generating optic anisotropy is added to a light source or onto an optical path extending from the light source to a polarization analyzer. This allows high precision analysis of the polarization state of light emergent from the polarization analyzer.
