Abstract

As an effective reconstructing technique to observe full-parallax holographic images in the wide viewing area, we have studied a projecting process of 3-D holographic images with the use of the spatial screen. Last year, as one technique to perform a suitable projection of the images, we have reported a projecting process of holographic 3-D images onto the underwater micro-bubble screen. Applying this technique, the stability of the images displayed in the screen seems to have been highly improved, however, as for the flickering of the images, much more improvement seems to be not so easy. Moreover, it requires a lot of water in the water tank, so that a complicated and a more weighty system has been needed. For this reason, we constructed a new spatial screen system employed the fog, in which a complicated structure and a lot of water was not required. In this report, we have discussed its effects to the reconstructed images through the holograms. In addition, in this study, we have seen that the system construction seems to be simple and not so weighty, and effective for suppressing the flickering of the images with higher resolution.
