ARAIZA E, M et al. Hologramas tipo Lohmann multiplexados. Rev. mex. fis. [online]. 2007, vol.53, n.4, pp.235-240. ISSN 0035-001X.

Based on Lohmann's method to create computer generated holograms (CGH) a multiplexing scheme is presented by making some modifications to basic cells, known as type I cells. With this variation, it is possible to storage up to 3 images in a hologram. At the reconstruction stage, the images are recovered simultaneously in the same direction and same diffraction order. Results show that the proposed procedure is effective for applications in image processing with some limitations.
