Patent ID: 8264774

Claim:
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.
