雾幕空间投影技术作为一种在大范围内以大视角显示全息三维图像的技术，已为人们所熟知。为了这样的目的，已经研究了其他各种各样的技术，然而，很难采取3D图像的侧视图。为了克服这个问题，我们面临的挑战是改进采用雾屏的全息3D显示系统。在本文中，我们将报道一种新的显示系统，该系统具有改进的喷射机制，补偿了雾屏的特性，并将两种方式的重建波结合在一起，给出了大量的三维图像。实验还表明，使用该系统可以在更宽的观看区域内更好地观察三维图像。由此，我们确定了采用薄雾屏的全息投影工艺显示大量三维全息图像的可能性。
As a technique for displaying holographic three-dimensional (3D) images in the wide region with a wide viewing angle, spatial projecting technique onto the mist screen is well-known. For such purposes, other various techniques have been studied, however, it has been difficult to take a side view of 3D images. In order to overcome this problem, we have been challenged to improve a holographic 3D displaying system employing a mist screen. In this paper, we shall report a new display system which has an improved jetting mechanism compensating the characteristics of the mist screen and gives volumeful 3D images by combining the reconstructed waves from two ways. It is also shown that by the use of this system, we can better observe 3D images in the wider viewing region than before. From this, we confirmed the possibility of a holographic projecting process adopted mist screen displaying volumeful 3D holographic images.
