Abstract (en)

[origin: WO2021141565A2] The present invention relates to a method for calculating and projecting 3-D holograms built in a multilayer manner. In particular, the present invention relates to a method for determining the image layers for forming the multilayer or multi-slice 3D volumetric images and the distances to be projected of said images and also for reducing the interlayer interference in holograms for forming the multilayer 3D volumetric images by means of the random selection of the phase of the image to be formed in each layer.
