We could maybe use beamers, which are perhaps small, while maybe inside a wall, and we could perhaps see our projection from the beamers by dimming the light with dimmers as a flat projection in the air.
It is especially suited for in the dark.
I assumed that a diffuse reflection is visible, due to it’s partly absorption into heat, which would mean that light from a beamer is too bright. We can focus the image in mid air of course.
Why would a diffuse reflection on a white screen (meaning that every colour is reflected) otherwise be visible, while the beamer’s projection isn’t in mid air? The answer is probably that the beamer’s light is white, so the white screen separates all the colours from eacother.
I supposed that we can use holograms as reversal film too, which would perhaps enable flat anisotropic 3D projections.
We could have do the same for 3D mid air projections with lasers & laser dimmers.
The picture on the right is fake though.
It doesn’t take much energy, but it is most of all not mutagen and retina damaging like the already existing method of exciting air.
I figured out that we can simply use a telivision screen in series with a positive lens too, to make an air projection, but I wonder how far we can project our projection, due to charge density as example, and also the capabilities of the lens. The charge density is however probably no problem.
We could also hide the small device (for mid air projections), or put it on top of our TV to create an outward 3D experience, and we could perhaps also put two of them to the sides of the TV. I came with the idea, becuase I saw outward 3D in the cinema.
It would be especially great if we could reverse the direction of the projection in mid air.
We would then be able to switch the direction of the projection.
We could also then wear a tiny device around our wrist, or maybe use some kind of remote, and last but not least: A BIG portable screen.
At first I assumed that it could be done if we enlarge the size of the light, so like decreasing the flux density. The light wouldn’t be too small to slip through the air, and I wonder if the air is actually white.
I thought about solving a duality. We would have to increase the reach of the light, while also preventing overlapping/oversecting of the image (overlapping/oversecting of the theoretical pixels), because the image would be blurred.
Clean water is normally also transparant, but I assume that it’s different.
It’s based on the assumtion that the speed of light through a vacuum and the speed through the air are the same. The blue sky is probably a different atmospheric layer.
I also assume that the lightspeed through the air and the vaccum are both, due to the refraction by the Higgs bosons. It’s such a shame that we can’t see them with our own eyes. My intuition tells me that XUV would perhaps be reflected by the Higgs bosons.
I supposed that we can get some kind of reflection by getting the angles & refracting indexes right for Snell’s law.
I haven’t focused on this subject though. I just hope that it turns around in front of us, so not at the transition. This could maybe happen if the refracion undergoes a similar path like the way how charges move by a magnetic field (Lorentz force), in contrast to what is thought, while it bounces back and forth too as well (I have read this principle for refraction once).
I hope that it propagates like this path, due to bouncing back and forth in an asymmetrical manner by the angle, but it could be impossible like this.
Dimming the beamer could maybe be the solution, but again maybe not.
