Abstract
we use packaged ray-tracing software to generate a complex Fresnel hologram. The principle is that the wavefront emitted from the object can be decomposed to Gaussian beams, and each of the Gaussian beams can be simulated to propagate in free space using the standard ray-tracing method. Thus, the amplitude as well as the phase of the resulting diffraction field can be obtained.
