Document Type and Number:
Japanese Patent JP2003519370
Kind Code:
A
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 optical sensors placed around and adjacent to the moveable object which transmit optical signals to a surface of the object and receives the optic signals when predefined marker means are sensed. The received optic signals are then processed by non-linear estimation techniques known to those of skill in the art to obtain the desired information.
