(under subclass 1) Subject matter in which an image reconstructed from one hologram is used as the object in making a second hologram.
(1) Note. Systems in which a holos:graphic analog to an ordinary optical element is used to shape or form a beam used to make a second hologram, but which does not by itself provide the object information for the second hologram are excluded. Such systems are classified based on the other claimed features in subclass 1 and its indented subclasses.
