Abstract
The method consists of transforming a digital two-dimensional image defined by a real function into a complex two-dimensional image defined by a complex function, oversampling the complex image, simulating the production of a diffracted image resulting from the diffraction of an optical wave by the oversampled complex image, and adding a complex field representing a reference optical wave to the resulting diffracted image to produce a hologram. The hologram produced in this way can be used to produce images in three dimensions or in telecommunications.
