Patent ID: 8243355

Claim:
Dynamic wave former unit with light modulator cells for spatial light modulation, said light modulator cells being arranged in a regular pattern in cell arrays, for setting separately both locally different phase shifts and different deflection angles in emitted partial light waves based on an incident light wave front, wherein Arrays of modulator cells are disposed serially in the optical path of the light wave front, which are controlled by cell controller means In a first cell array such that the modulator cells discretely realize a phase shift with a continuous phase value, and In a second cell array (A 2 ) such that the modulator cells realize a prism function with a continuous direction value (αm) for the partial light waves, And in that means which realize a focusing function for the emitted wave front are disposed in the light path of the optical unit, said focusing function directing the partial light waves of the optical unit at a common position in the exit pupil.
