Abstract

A novel design method of diffractive optical element for shaping Gaussian Schell model beams is investigated. In the design, it is important to solve a deconvolution problem for obtaining diffraction image with edge-sharpness degraded by the convolution effect of the partially coherent Gaussian Schell model beam. In this paper, a simple heuristic approach to the deconvolution problem is addressed. It is shown that an extra rim pattern around the target diffraction image can lighten the unwanted edge-blur of the diffraction image. The algorithm for generating the extra rim pattern is explained.
