| Abstract: | The possible use of commercial fine-grain films for computer-generated binary holograms is described. Three different types of film are used. Image quality improves with film resolution but if the resolving power is higher than a minimum value needed for the phase level resolution, the contrast (γ value) of the film has a pronounced effect on the quality of the image reconstructed optically from the hologram. The possible generation of binary holograms by computers with reduced central memory is also studied. |
