An electro-optic speed sensor for sensing the speed of rotation of a rotating member includes a magnetic core and a coil coupled magnetically to the core for sensing disturbances in the magnetic field of the core caused by the rotation of the rotating member. The disturbances in the magnetic field generate an electrical pulse in the coil, which is transmitted to an electrical circuit including one or more light emitting diodes, which emit a pulse of light in response to the electrical pulses. The light pulses are transmitted to a resolution circuit through a fiber-optic cable. |
