Electro-holography equipped with a spatial light modulator (SLM) is considered to be an important basic technique for 3D-TV. However, the resolving power of ordinary SLM seems to be very low, and so it looks very difficult to satisfy the space-bandwidth product (SBP) condition. It is unfavorable since the values of the size and the viewing angle of the reproduced images are known to be restricted. We tried to manage this problem by introducing several processes using a spatial screen of a mist flow or a micro-bubble, and discharged air plasma. In these processes, since we have jetted out the scatterer into the space directly, fluctuation reducing process of the screen has come to be an important problem. In this paper, we shall report that, to improve the stability of the mist screen, a spatial screen employed a bladeless fan (without blades) is introduced, and a challenge is made for holographic projected images to be presented in an extended display area of the screen. As this result, we confirmed that an effective display area is exactly enlarged, and a performance of highly bright projected images is carried out by this new system.
