This report presents the results of computer simulation images for image-type Computer-Generated
Holograms (CGHs) observable under white light fabricated with an electron beam lithography system. The simulated
image is obtained by calculating wavelength and intensity of diffracted light traveling toward the viewing point from the
CGH. Wavelength and intensity of the diffracted light are calculated using FFT image generated from interference fringe
data. Parallax image of CGH corresponding to the viewing point can be easily obtained using this simulation method.
Simulated image from interference fringe data was compared with reconstructed image of real CGH with an Electron
Beam (EB) lithography system. According to the result, the simulated image resembled the reconstructed image of the
CGH closely in shape, parallax, coloring and shade. And, in accordance with the shape of the light sources the simulated
images which were changed in chroma saturation and blur by using two kinds of simulations: the several light sources
method and smoothing method. In addition, as the applications of the CGH, full-color CGH and CGH with multiple
images were simulated. The result was that the simulated images of those CGHs closely resembled the reconstructed
image of real CGHs.
