Abstract
A magneto-optical current sensor for measuring current flowing through a conductor, characterized by at least two components. One component is parallel to the direction of current flow and is proximate to a source of magnetic field. The other component is perpendicular to that direction and includes a surface in contact with said one component. One of the components having a reflective surface for reflecting a polarized light beam between components whereby a light signal is produced that is compensated for temperature, loop degradation, and linearity.
