Abstract
A novel method to design diffractive optical elements, based on the spherical wave propagation and superposition, is presented in this paper. Underlying theory, practical considerations, results and limitations of this method are presented based on computer simulation experiments. Diffraction patterns produced by such diffractive optical elements are shown for binary intensity objects described either by the Cartesian coordinates of their non-zero points or by image format files. The method by itself stands as an effective method to calculate phase diffractive elements for free space optical interconnection between an array of point sources and an array of point detectors, but is shown to be also useful to generate binary intensity objects. The optimization of the phase function which describes the phase diffractive element is also demonstrated by means of a micro-genetic algorithm.
