Energetic efficient synthesis of general mutual intensity distribution

The mutual intensity distribution of a light beam may contain available inf ormation. The task of encoding a given mutual intensity distribution is add ressed in this paper. Various approaches for encoding the mutual intensity function have been previously proposed. However, all of them provide low en ergetic efficiency and commonly require sophisticated production methods. T he idea of using a phase-only filter for performing this synthesis is hereb y investigated. The proposed method is numerically examined for the case of placing the mutual intensity generating filter in the fractional Fourier d omain.
