Description

ABSTRACT:
A holographic laser beam deflector has an approximately flat field scan. The scan is produced by illuminating a rotating hologram on a circular surface by a laser beam. The virtual source of the illuminating beam is offset from the center of rotation of the hologram. The hologram is produced by interference of a pair of coherent laser beams, each beam having a source or virtual source on a line containing the rotational center of the surface of the hologram, one source or virtual source outside the surface, the other inside. The virtual source for the inside beam is also displaced from the center of rotation.
