Abstract: 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.
