ABSTRACT:
The invention relates to an element for the combined symmetrization and homogenization of a beam of rays and to a method for designing an element of this type. One object of this invention is to propose an element and a corresponding design method by means of which a beam of rays with any desired intensity distribution is shaped from a beam of rays with an inhomogeneous intensity distribution. In particular, the intention is to transform a beam of rays with an elliptical intensity distribution into one with a different elliptical intensity distribution. For this purpose, the invention provides a phase element for the simultaneous circularization and homogenization of anisotropic intensities of electromagnetic waves.
