On a study of a holographic mist screen system improved by stable mist flow, and a reformed screen system reproducing highly bright holographic projected images in an extended effective display area

In this paper, we made a basic study for the improvement of the screen system to raise the stability of mist flow and to produce highly bright reproduced images without using mist controlling fan. As this result, we succeeded in constructing a reformed screen system adopted a nozzle producing strongly directed mist flow with voluminous form to the depth direction. It enabled us to generate a mist screen of the form like air curtain. We constructed a system for raising the stability of the screen adopted one unit of ultrasonic vibrator, and another system for raising the brightness of recovered projected images adopted two units of ultrasonic vibrator, and confirmed the effectiveness of these systems. Like this way, we achieved improvement in stability and brightness compared to previous systems.
