Patent ID: 7548375

Claim:
A device for influencing light, the device comprising: a first array of lens systems, through which the light to be influenced can at least partially pass; a first phase-modifying array for modifying phases of the light having passed through said lens systems of said first array of lens systems; a second array of lens systems, through which the light having passed through said first phase-modifying array can at least partially pass, said second array of lens systems being disposed in the device so that a plurality of local intensity maxima of the light to be influenced can be created in a vicinity of or before said second array of lens systems in a propagation direction of the light to be influenced; a first lens system disposed between said first array of lens systems and said second array of lens systems, said first lens system being configured to Fourier transform the light to be influenced; and a second lens system disposed between said first lens system and said second array of lens systems, said second lens system being configured to Fourier transform the light to be influenced; said first phase-modifying array being disposed between said first lens system and said second lens system in said propagation direction of the light to be influenced; said first phase-modifying array being disposed in or in a vicinity of an output-side Fourier plane of said first lens system and in or in a vicinity of an input-side Fourier plane of said second lens system.
