ABSTRACT:
Disclosed is a magnetic fiber optic scanner which includes a flexible optical fiber of predetermined length, having one end fixedly supported in a cantilevered fashion, and having an opposite end that is unsupported and free to move. A magnet is rigidly mounted on the fiber near the unsupported end to there produce a magnetic dipole moment parallel to the length of the fiber. A grid like array of electrical conductors lies in a plane that is perpendicular to the fiber and is spaced apart from the unsupported end. By passing current through selected ones of the conductors, localized magnetic fields are produced that react with the dipole moment to position the unsupported end of the optical fiber in offset alignment with the selected conductors.
