Rotation sensor for gyroscopically mounted rotor.

摘要

The invention proposes remote rotation sensing of a gyroscopically mounted rotor (40) by utilizing a single fiber optic (50) between a light reflector (35) on the rotor and a light source/light detector (64,68). The single fiber optic (50) provides transmission for both source light energy in a first direction and reflected light energy in the opposite direction. A second embodiment provides a discontinuity (51,53) in the fiber optic to allow for relative movement.
