A contactless precision, optical distance and angle measurement method and
system optically measuring the position of a moveable object, the bending
of the object, the torque applied to the object and the object's
rotational velocity. The present invention includes a plurality of
sectioned fiber optic placed around and adjacent to the moveable object
that transmits optical signals to a surface of the object and receives
the optic signals when a predefined marker or a reflective area is
sensed. Another embodiment utilizes a sectioned optical assembly which,
via alternate means, produces equivalent optical measurements. The
received optic signals are then processed using mathematical computations
that are facilitated through pre-characterization of the sensor response
against a reflective material identical to that of the marker or
reflective area.
