Paper Abstract

We have reported that viewing angle of the computer- generated hologram can be expanded with lensless Fourier transform hologram. It however, requires a laser to illuminate the CGH for reconstruction. In the previous paper, we have proposed that making the second hologram for white-light reconstruction. The reconstructed image from the first hologram is used as the object beam of the second hologram. The second hologram can be either transmission or reflection hologram, which depends on the direction of the reference beam. In this report, we extend this method to make the full-parallax computer-generated holographic stereogram. At first, we calculate the master hologram consists of elementary holograms. Each elementary hologram is calculate by Fast Fourier Transform of perspective 2D image. Then, the transfer hologram can be made from the master CGH with single exposure. In the experimental result, we obtain full-parallax computer-generated holographic stereogram with 20 degrees of viewing angle and 10 mm X 7.6 mm image size.
