A device for holographic reconstruction of three-dimensional scenes
includes optical focusing means which directs sufficiently coherent light
from light means to the eyes of at least one observer via a spatial light
modulator that is encoded with holographic information. The device has a
plurality of illumination units for illuminating the surface of the
spatial light modulator (SLM); each unit comprises a focusing element
(21/22/23 or 24), and a light means (LS.sub.1/LS.sub.2/LS.sub.3 or
LS.sub.4) that emits sufficiently coherent light such that each of these
illumination units illuminates one separate illuminated region (R1/R2/R3
or R4) of the surface, whereby the focusing element and the light means
are arranged such that the light emitted by the light means
(LS.sub.1-LS.sub.4) coincides close to or at the observer eyes.
