A novel algorithm is presented for hidden-surface removal in digitally synthetic holograms. The algorithm is
able to work with full-parallax holograms and remove obstructed fields in the object wave emitted from threedimensional
(3-D) surface objects. This algorithm is initially discussed as a rigorous procedure to obtain fields
behind a tilted planar surface by using the rotational transformation of wave fields, and finally results in the
silhouette approximation for reduction of computation time. Reconstructions of holograms created by using the
algorithm are demonstrated.© (2004) COPYRIGHT SPIE--The International Society for Optical Engineering. Downloading of the abstract is permitted for personal use only.
