Abstract
A method and device for influencing light, include a first array of lens systems through which the light to be influenced can at least partially pass. A first phase-modifying array modulates the phases of the light which has passed through the individual lens systems of the first array. A second array of lens systems is provided through which the light phase-modified by the phase modifiers can at least partially pass. The second array of lens systems causes a plurality of local intensity maxima of the light to be created in the propagation direction of the light in the region of the second array of lens systems. A first lens system is disposed between the first array of lens systems and the second array of lens systems and a second lens system is disposed between the first lens system and the second array of lens systems. The first phase-modifying array is disposed between the first and second lens systems.
