Beschreibung
Zusammenfassung:	The invention relates to a light modulation device for a complex-valued modulation of linearly polarized incident light, comprising a first light modulator, a subsequently arranged second light modulator and at least one polarizer, where the first light modulator and the second light modulator are configured as phase modulators, where a modulation axis of the first light modulator is aligned at an angle to the modulation axis of the second light modulator, and where the polarization direction of the light incident on the first light modulator and the polarization direction of the polarizer are respectively aligned at predetermined non-90° angles with respect to the modulation axis of the first light modulator and the modulation axis of the second light modulator.
