Abstract
A new technique useful to store several images in a detour computer generated hologram, is described. The method basically works as follows: every hologram cell is sectioned in vertical segments, which then are used to encode different objects, one per subcell. In the reconstruction all images appear simultaneously in the same diffraction order. Also, by the use of spatial filters at the hologram plane, it is possible to select any desired image. The method allows encoding up to 4 objects. The experimental results demonstrate the effectiveness of the suggested procedure.
