Abstract:
Optical beam former for generating an emerging light beam from an incident light beam, the optical beam former including: a condenser lens array including several condenser lenses; and a projection lens array arranged in parallel to the condenser lens array and including several projection lenses; wherein exactly one of the projection lenses is assigned to each of the condenser lenses so that several optical channels are formed and so that each of the several optical channels generates a partial light beam of the emerging light beam, said partial light beam emerging in an angle-of-emergence range with a partial intensity distribution that is homogenous with respect to an angle of emergence, from an incident partial light beam, wherein the admissible angle-of-incidence ranges of the optical channels have the same size as to the magnitude in a plane extending in parallel to the optical axes of the condenser lenses; and wherein the angle-of-emergence ranges of at least two of the optical channels are different so that an intensity distribution with respect to the angle of emergence includes several regions having a homogenous intensity in a far field of the emerging light beam.
