for the that some of the core more than 2 this is and from
the point this is but the the major that have been assigned to monitor the progression of the and the during the time of of the already small and the stage for all I see that the prediction kind but a means of gathering tough size of program uh is you and to and most of the users that is necessary to spirit fact they so the rest of the screen you through the screen designed to be from the right side of units God giving up the cost of this in this paper the worked up but it's really missed the screen we grow control it is considered and that 10 the Catholics always that image is considered the this is at the heart of the
matter is all of these so discouraged and for program use of the constructed by the results and that's the and the size of the component material use of
and micro on the graph theory index from point to in this case the the lots of new discoveries and there a need kept up by this relation this case as from scattering and into the real problem sort of art on the guy is scared about this new material on we can see this scattering this since case of our consultant degrees pieces of different form was operation on so this case power but we don't see you in this space the
target concept but in this case uh kept up to get the material will move the 2 12 for what the following by gravity and so what are we the broad for of modular moved In this case native competence through so we use this of sodium is being
constructed treating Mr. steering reason problem draw this is also the the screen and so the in this case
that the that so you the screen in this area will be that the system using a broken barrel of Anthony discrete the thought of as a result of the endospore and program these predictions for the in this area and so all this is looked at a group of about what a small world and so this is what what small nature and this is that they controlled control but the actually most of the small size what what does the fact and we can
see that the units of g over you will use distribution would be part of the of the fission or use of force is more mirrors and this is hundreds of point minor injuries on excel size for
16 risks and this is the horror and this goes on to be some program 1 that's
something that you can do so all we can see that the image this is on the left side is that result from of there is too broad and this area small we can see that so over the course of the measures we control of
it becomes which Russia saw what makes the next at that stage uh we can't construct the power of the Ministry spirit this is looking at each new chest CT scanning them so that that's good for falls the government richer the ones that we think the construction of men as a screaming this
decision we look for industries these this is the system In this sort of most the models who he areas conspiracy complement not small but it comes from here and spread from this most this is the looked inside of system so in this area is the units of the screen and become richer on we can't come from my grandmother of support for all moved from the most this becomes a state suspicion becomes more not to the kind of stuff because so for so why spread so in this area not to we we use this area for the screen because the the fastest faster speed all this small or what do you need to depend on the screen size screen size is about 2 important from you know it's some we rewrite this discrete and so this area of our density concentrative sort of we do not look at the program and the cost of indices that orders just couldn't reason all control but marriage it's moving to vision and then this is that the boring spinning wheel is problem have you made to model the possibility disposed and then this is artist research problem at all this is this is not desirable Catholics we met over the course of the we can improve so the Conference in a context in this had the of
conclusion on the screen in his posthumous to tribute hurt true form what about restoring we did have you not see this on the rest of this first one we group over there with the unit and then we perform from now we we consider about what the difference of more material did because of that depending on what is dependent on the small size of a small amount of material we hope to the rural so it is to be reused right you know with the size of that using these fine particles with discrete and wouldn't without that we can have 1 question before we break for coffee yes there is is no more so there are the latest altogether what happens to the water in your mystery most a really really really year water because on the German word of the lord of the men in the wilderness of people in there and so and so is and Future but the rest of prior to the filing of material point in the past on very good quality from but for a lot of energy through Europe all not the problem is that the kids and maybe we just take 1 last question how big is this we that this kind of thing is that my so the types sentence back and the so you have this from that that is there any more questions you can ask of the the center of that later maybe will break for coffee not just before we do I like to make an announcement at the center of modern optics which is just up the the street on the right hand side will be open during the breaks now until the end of the conference for anyone who would like to see some holograms made on the Silver Cross emulsion so that's just up the street on the right hand side and otherwise so if we aim to be back perhaps the top possible just before half past 3 and half years of

Abstract Recently, many types of 3-D displays have been developed. We would like to see 3-D moving images with comfortable and more expanded depth. Holography is different from the other 3-D display because a natural stereoscopic image can be obtained. We previously developed an electro holographic display using a virtual image. But the viewing area is small because the pixel size of the LCD is not so small. Now, we have developed a projection type electro-holographic display system. For projection type holography [1] a 3-D screen has to be used in order to project the reconstructed image clearly and for the viewing angle to become wide. We developed an electro-holographic display system using a mist 3-D screen. However, a reconstructed image with a mist 3-D screen flickers due to gravity and air flow. Then we considered how to reduce the flicker of the image, and we found that flicker could be reduced using a flow controlled nozzle. Hence, at first we considered the most suitable shape of 3-D screen, and then we constructed the array of flow controlled mist 3D screen. Through our experiments, we were able to obtain a considerably high contrast 3-D moving image and to achieve a viewing area of more than 30 using this flow controlled nozzle attached water particle 3-D screen and make clear the efficiency of this method.
