Abstract :
In this paper, a new technique for occlusion processing is proposed in computer holography. The new technique based on the silhouette method is very fast as compared with the conventional methods. This technique allows us to remove hidden-surfaces of self-occlude objects and makes it possible to reconstruct fine spatial 3D images that are comparable to that in classical holography. The performance and optical reconstruction is reported.
