Abstract : The patent generally relates to tracking and more particularly to a laser beam scanning system adaptable for use in air and underwater tracking systems. This is accomplished by providing orthogonal scanners in which a rod bundle of fiber optic elements are scanned in a linear (one-dimensional) direction to apply a beam to a narrow rectangular bundle of fiber optic elements that are in turn scanned orthogonally to the scan of the rod bundle of elements. The scan of the rod bundle of elements can be in the order of 500 times as rapid as the scan of the narrow rectangular bundle. In neither of the rod bundle nor rectangular bundle scans is there a fly back time in which the fiber optic components are not conducting, as in television where the electron beam is blanked during fly back. The driving elements can be either electromagnetic or piezoelectric and are rigidly attached to the fiber optic components.
