Abstract

This paper establishes how the method of representing an object affects the imaging properties of synthesized holograms. It is shown that, if a hologram is synthesized by representing an object on the basis of its spatial-frequency analysis, this disrupts the structure of the reconstructed image—i.e., it causes the reconstructed image to be displayed in the form of a collection of detached points. In order to eliminate the detected disturbances, it is proposed to synthesize the holograms with a discretization period of the object that is a factor of 4 smaller than the period determined from a spatial-frequency analysis of the hologram. It is shown that using the proposed representation of the object does not substantially increase the time to synthesize a hologram.
