| 摘要： | Two approaches for a fiber critic wheel rotation sensor down to zero RPM have been pursued. The first approach using magnetic domain diffraction of li^ 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 Farads rotation of light within the BIG crystal has ben developed and a working sensor has ben demonstrated. Both sensors rely on a magnetic tone ring which is mounted within the bearing of the wheel. |
