<p>An electro-optic speed sensor for sensing the speed of rotation of a rotating sending unit which includes an optical switch transducer for sensing disturbances in a magnetic field caused by the passage of a rotating magnetic sending wheel on the rotating member. The optical switch transducer uses a Faraday material and provides its signal by rotating the polarity of polarized light reflected within the transducer. The disturbances in the magnetic field generate an optical signal resulting from changes in the Faraday rotation.</p> |
