Abstract

A novel optical configuration for a current sensor utilizing the Faraday effect is described. A common-path optical-fiber heterodyne interferometer is used to greatly reduce noise produced by environmental effects. A miniature sensing element at the distal end of the fiber allows remote magnetic field or current measurements to be made.
