Method and apparatus for generating reconstructions of information encoded in ambient light modulators

Method for the generation of reconstructions of information encoded on spatial light modulators by way of illumination with coherent incident waves, where the information is encoded in controllable pixels of a pixel matrix with an inter-pixel matrix in the form of an electrode grid, which is contained in a spatial light modulator, containing the following steps:

• Splitting of the incident wave into at least two incident sub-waves,
• Modulation of the incident sub-waves with the help of selected apodisation functions so as to form modulated incident sub-waves,
• Direction of the modulated incident sub-waves towards the corresponding, spatially separated and pixel-matrix-shifted spatial light modulators,
• Diffraction of the modulated incident sub-waves at the encoded pixels of the respective spatial light modulators,
• Additive combination of the sub-waves emitted by the respective spatial light modulators to form one common emitted wave, and
• Transformation of the emitted wave into the Fourier plane with the help of a projection system.
