The present invention relates to a device for combining light beams which interact with adjacently arranged pixels of a light modulator. The present invention furthermore relates to a device for beam combination and to a spatial light modulation device for complex-valued modulation. The invention relates to a device for beam combination, and to an optical arrangement of polarization-sensitive component parts which allows complex-valued modulation of a light field by means of a phase-modulating light modulator and a beam combiner, which is insensitive to changes in the incidence direction of the illumination wave. This document furthermore also relates to various arrangements of reflectively operating light modulators.
A device for combining light beams which interact with adjacently arranged pixels of a light modulator, wherein the light modulator comprises a multiplicity of pixels and is driven in such a way that two adjacent pixels respectively form a macropixel, wherein a beam splitter is provided in relation to a macropixel, which is configured and arranged in such a way that incident light beams are thereby split into a first subbeam and a second subbeam, in such a way that the first subbeam propagates in the direction of the first pixel of the macropixel and the second subbeam propagates in the direction of the second pixel of the macropixel, wherein a first structured beam influencing component is provided between the beam splitter and the light modulator, which is configured in such a way that the first subbeam can thereby be influenced in a different way to the second subbeam, wherein the first and second subbeams pass after interaction with the respective pixel of the macropixel through a second structured beam influencing component, which is configured in such a way that the first subbeam can thereby be influenced in a different way to the second subbeam, wherein a beam combiner is provided, which is configured and arranged in such a way that the first subbeam and the second subbeam can thereby be combined, and wherein a beam selector is arranged between the light modulator and the first or second structured beam influencing component, which is configured in such a way that at least one of first and second subbeams which does not belong to the macropixel are thereby blocked.
