Simulation of Image Reconstruction based on Point Light Source Method from Computer-Generated Hologram using Fourier Transform Optical System

Abstract

In numerical simulation of image reconstruction from computer generated holograms, Fresnel diffraction integration using FFT is generally used in order to calculate propagation of light waves. There are disadvantages of impairing accuracy and flexibility of calculation in FFT. Therefore, we propose simulator of image reconstruction based on point light source method of computer-generated holograms using Fourier Transform Optical System. It enables to calculate images with high accuracy and flexibility. By the experiments, we confirm the method simulates reconstruction process successfully.
