In this paper, we have investigated the real image reconstruction from computer-generated hologram (CGH). The reconstructed real image is excellent as a display to give a strong three-dimensional appearance to an observer. However, it is difficult to get enough diffraction angles so that high space resolution is demanded for the real image reconstruction of the CGH. Therefore the reconstructed image usually does not have enough viewing area and size. In this report, we get real image that has wide viewing area which is using conjugate source as reconstruct source of the CGH. However this method doesn't give an accurate reconstructed image from the CGH. Therefore, we changed object data to use for a calculation to suitable form. We made CGH with these data and output a high-resolution hologram with a fringe printer.
