摘要：The invention relates to a controllable illumination device for anautostereoscopic or holographic display, which illumination device contains anillumination matrix of primary light sources having at least one luminous element perlight source and a controllable light modulator (SLM) and a reproduction matrix. Acomputer-generated hologram (CGH) illuminated by the primary light sources (11, . . . ,1n) is coded on the controllable light modulator (SLM) and generates, in at least oneplane downstream of the SLM, a matrix—reconstructed from the computer-generatedhologram (CGH)—of secondary light sources (2) having a secondary light distribution forthe purpose of illuminating the reproduction matrix (4) and for the purpose of focussingin light bundles onto each eye of the viewer via an imaging matrix. The CGH is calculatedand reconstructed on the basis of the number of and the positions of the viewers and thesystem parameters. Owing to the reconstruction of the secondary light sources in aplurality of planes, it is possible for the image information of the display to be trackedfor the viewers not only in the case of lateral movements but also in the axial direction.
