Abstract: Various embodiments of the present invention are directed to external, electronically controllable modulators. In one embodiment, a modulating device (100,400) includes a first electrode (104,404), a second electrode (106,406), and an active region (102,402). The active region is configured so that at least a portion of the active region is disposed between the first electrode and the second electrode. Applying a voltage of an appropriate magnitude and polarity to the electrodes changes the conductivity of the active region which in turn shifts the phase and/or amplitude of electromagnetic radiation transmitted through the active region.

Abstract: The invention relates to a method for reconstructing a three-dimensional scene in a holographic display. In said method, the 3D scene that is to be reconstructed is decomposed into object points, and one respective object point is encoded as a sub-hologram in the light modulator. Processor means and reconstruction means are provided for calculating and encoding as well as for reconstructing the 3D scene in order to overcome known drawbacks encountered when encoding a hologram and holographically reconstructing the 3D scene in holographic display devices. According to the proposed solution, processor elements are provided for generating a movable two-dimensional grid in the light modulating means (L), forming groups of object points (OPGm) from grid-related object points (OPn), and sequentially encoding the holograms of said groups of object points (OPGm), by means of which intrinsically coherent partial constructions of the groups of object points (OPGm) are generated in a rapid sequence, said partial constructions being incoherent relative to one another. The wave fronts of reconstructed object points are sequentially superimposed within a visible range such that the reconstruction of the 3D scene can be seen as a time-averaged reconstruction.
