Abstract

Instead of the rectangular binary masks introduced by A. W. Lohmann, D. P. Paris and B. R. Brown to construct holograms by a computer, the holograms may be computed using circular binary masks. The new holograms are equivalent to ordinary holograms only with regard to the image reconstruction. In this work, circular binary mask techniques have been established theoretically and verified experimentally.
