Abstract

<p>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. As one technique to perform a suitable projection of the images, projection of holographic 3-D images onto the underwater micro-bubble screen is well known. Applying this technique, the stability of the images displayed in the screen seems to have been highly improved, however, as for the flickerling of the images, much more improvement seems to be not so easy. For this reason, we constructed a new spatial screen system employed fog filled in the tank. In this report, we have discussed its effects to the reconstructed images through the holograms. We have seen that effective for suppressing the flickering of the images with higher resolution.</p>
