ABSTRACT:
A fiberoptic velocity transducer for use in determining the rotational speed of an object and comprising a magneto-optic material coated with a dielectric material that operates to selectively pass light energy having a first range of wavelengths, and to reflect light energy having a second range of wavelengths, so as to make the light energy with the second range of wavelengths available as a reference signal, the magneto-optic material functioning to cause a Faraday rotation in the light energy having the first range of wavelengths that is characteristic of the speed of the rotating object.
