Claim 0:
1. A method for generating a light field in a specified work region using an at least partly coherent light source, comprising:
providing light from the light source to at least one modulator which impresses different changes in at least one property of the light on different components of the light;
controlling the at least one modulator by a zero control pattern such that the summation of the amplitude distributions of the light components, which were guided via the modulator, have zeros at at least two positions that are specifiable independently of one another within the specified work region, wherein the zeros each adjoins regions in which this summation of the amplitude distributions differs from zero; and
guiding the light from the at least one modulator into the specified work region.
