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.
