FIG. 3 is a diagram showing a state of scattered light when light is projected onto small water droplet particles. As shown in FIG.
When the light is projected onto the water droplet particle 31, the intensity of the scattered light 33 directly reflected by the outer surface of the water droplet particle 31 causes the forward scattered light 35 that is refracted or transmitted through the water droplet particle 31 to go out. It turns out that it is much stronger.

測定結果に基づいて構成された。FIG. 4 is a diagram showing a measuring method performed for demonstrating the phenomenon shown in FIG. In the figure, light is projected onto the fluid screen 40 in the direction of arrow C, and scattered light scattered on the front surface (light traveling direction) and the back surface of the fluid screen 40 is symmetrical to the fluid screen 40 perpendicularly. It was decided to measure with two illuminance meters 41 and 43 arranged at the position. When the ratio of the scattered light intensity (E 1 ) measured by the illuminance meter 43 and the scattered light intensity (E 2 ) measured by the illuminance meter 41 is calculated, for example, E 2 / E 1 ≈50
Became. In other words, it was revealed that extremely strong forward scattered light was obtained with respect to the light reflected backward. The present invention was constructed based on the measurement results.

れている。Next, projection devices 19 and 21 installed on both sides of the fluid screen 25 respectively project light on both sides of the fluid screen 25 to form an image on the fluid screen 25. 2A and 2B are diagrams showing the projection timing of light projected from the projection devices 19 and 21 onto the fluid screen 25. FIG. 2A shows the projection timing of the projection device 19, and FIG. 2B shows the projection timing. The projection timing of the apparatus 21 is shown. As shown in the figure, both projection devices 19 and 21
Projection timing is reversed, and when the projection device 19 is on and is projecting light, the projection device 21 is off and does not project light, and the projection device 19 is off and emits light. When not projecting, the projection device 21 is turned on and projects light. Further, the on / off cycle t is set to be shorter than the afterimage period of the naked eye that remains in the naked eye until the next time the image projected on the human naked eye is turned on when projection is on.

るからである。The projection timings of both projection devices 19 and 21 are set in this way because if both projection devices 19 and 21 simultaneously project light onto the fluid screen 25, both projection lights interfere with each other in a water droplet. This is because all the images become unclear.

像はいずれも鮮明となる。As described with reference to FIG. 3, the forward scattered light is extremely strong as compared with the scattered light reflected directly backward,
For example, when the projection timing of the projection device 19 is on and the projection timing of the projection device 21 is off, almost all the light projected from the projection device 19 is scattered in the traveling direction of the light by the fluid screen 25, and is directed toward the opening 23a. It does not go to 23b. That is, the reflected light has almost no practical effect, and the images projected on both sides of the fluid screen 25 are clear.

It is configured so as to be projected and imaged on the fluid screen 25 later. Here, the two-reflective rocking device 27, 28
The mirrors 27a and 28a of FIG. 2 swing vertically and horizontally, and the swing is performed as follows.

After being reflected by 8a, it is projected and imaged on the Y portion of the fluid screen 25. The image formed on the X portion is rotated in the direction of arrow A in the figure by swinging the mirror 27a. The image formed on the Y portion at the same time is reflected by the mirror 2
By oscillating 8a, it rotates at the same rotational speed in the direction of arrow B in FIG. In other words, the two images do not overlap each other, and therefore a clear image can be realized. Both mirrors 27
The swing control of a and 28a is performed by the projection position moving means provided in both reflection swing devices 27 and 28.
