Abstract

Recently, we have reported a magneto-optic angular displacement (MOAD) sensor where both the incident and reflected laser beams pass through a magneto-optic (MO) film. In this letter, we report a modified MOAD sensor where only a reflected laser beam passes through the MO film. With the modified configuration, the modified MOAD sensor is a truly remote sensor such that the MO film can be located close to the detector and far from the sample. Furthermore, the modified sensor system can measure angular displacements with an improved resolution of 1×10−3 deg, which is ten times better than that previously reported.
