Three-dimensional non-contacting sensor for tracking the spherical motion of a body.
Researchers at the University of California, Davis have developed a real-time, three-dimensional angular motion tracking scheme that determines the absolute orientation, axis of rotation and angular speed of a body rotating about a point, which is fixed relative to the sensor.
The scheme is based on a single tri-axial fluxgate magnetometer. The algorithm takes the three-dimensional flux density measurements from the magnetometer and calculates the angular motion information at each sampling. UC Davis researchers have developed an apparatus and tested the feasibilty of this scheme, and have demonstrated the scheme's capability of non-contact angular rate sensing.
