Method and device for the synthesis of holograms |
摘要 |
<p>The invention concerns a method which consists in transforming (E1, E2) a two-dimensional digital image defined by a real function into a complex two-dimensional image (IM2) defined by a complex function, oversampling (E3) the complex image (IM2), simulating (E4) the production of a diffracted image (IM4) resulting from the diffraction of an optical wave by the oversampled image (IM3), and adding (E5) a complex field representing a reference optical wave to the resulting diffracted image (IM4) to produce a hologram. The resulting hologram can be used to produce three-dimensional images or in telecommunications.</p> |
