Abstract
We develop a novel and efficient method to simulate diffraction patterns in the far field and in the Fresnel region when the phase counters of a quantized diffractive optical element are approximated by arbitrary polygons. Approximation causes signal errors whose effects have not been extensively studied so far. We take the polygonal shapes into account without any further approximations in the simulation, in contrast to calculations based on direct application of the Fast Fourier Transform. The method is applied to diffractive Fresnel lenses, axicons and gratings with finite size.
