Abstract

The invention of the kinoform (Ref. 1) as a form of on-axis computer-generated holo-gram has stirred considerable interest. The basic observation was that a photographic plate of optical density D(u,v) could be bleached to give an amplitude transmission of eiD(u,v); and therefore, if we contrived to achieve D(u,v) = 0(u,v), we could gene-rate the wavefront ei0(u,v). For most interesting wavefronts there is no way of generating D(u,v) optically, so it is usually recorded by a computer-plotter arrangement.
