Abstract:
1. A holographic imaging display, comprising: at least one illumination means for generating a sufficiently coherent illuminating wave front, at least one phase modulator on to which predetermined control values for reconstructing the wave front of a three-dimensional scene (3D scene) are encoded; an imaging system for the imaging and/or Fourier transformation of wave fronts; and a processor at least two imaging means, where a first imaging means, for imaging the illumination means and for Fourier transforming actual wave fronts which are modulated in the phase modulator, is followed by a second imaging means, which serves as a screen, where the plane of the screen is a Fourier transformation plane for the computations with the iterative Fourier transformation algorithm, and where the plane of the phase modulator is the other Fourier transformation plane, and is provided for imaging the wave front which is encoded with the control values into the visibility region; and a filter whose aperture or an image of the aperture defines in the plane of the screen a transformation area, which comprises the reference wave front defined by N complex values of the 3D scene to which the complex values of the actual wave fronts transformed by the phase modulator are approximated by way of iterative computation using the Fourier transformation algorithm.
