Abstract
In the presentation of 3D volumetric holographic images, spatial projection technique with the use of mist screen seems to be very effective. However, in the previous study for this technique, complicated formed nozzles and a complicated optical system have been required. In this paper, we shall introduce a new mist screen display which enables us to present spatially volumetric holographic images in a more easier way. It has adopted only one fan which produces a stable spiral flow of the mist with the aid of mist-flow controller. Mist-flow controller is used for arrangement of the flow of the mist. It suggests that it gives us in a more easier way the volumetric holographic images in the mist screen in the spatially projected process, and it is also useful to suppress the fluctuation of the images generated when wind blows in the cross direction.
