Fiber-optic wheel rotation sensor. Final report CRADA No. LA93C10086
Two approaches for a fiber optic wheel rotation sensor down to zero RPM have been pursued. The first approach using magnetic domain diffraction of light in a BIG (bismuth iron garnet) material has been demonstrated and the further technical developments to routinely produce a practical product have been identified. The second approach involving Faraday rotation of light within the BIG crystal has been developed and a working sensor has been demonstrated. Both sensors rely on a magnetic tone ring which is mounted within the bearing of the wheel.
