Is there a decent hologram technique that can create volume with some technique ? The problem with holograms is that they can only use light that has to be casted on a surface except for mid-air ionization technique which is shit.
Is there a way to block or occlude the light coming in mid-air to fake volume ? What are the latest the most modern hologram techniques ?

You might like this, OP.
I'm not an expert on the subject by any means so forgive me if there are any flaws in my physics.
That being said I have considered the subject and I have formed a hypothesis that it might be able to create holograms using a technique wherein lasers are scattered at various points in 3d space by way of a non uniform electric field.
The basic idea is that a focused laser grid is projected into a region, and by very very precise manipulation of a magnetic field within that space you can cause the lasers to defocus at chosen points causing light scattering just as if they had reflected off of a solid surface. Obviously the main problem would be precision control of the em field itself. It would be very difficult to get the desired wavelength reflection so color would be a problem, also you would basically have to sculpt the field into the desired shape which might not even be possible to begin with, and even if it is creating fine details would be absurdly difficult. Basically it might work for geometric shapes, but images like a human face might be out of the question

yeah, this is what I meant by ionizing particles in mid-air. Anything with white background and it doesn't work.

project it onto a tube of fog.

>I'm not an expert on the subject
then why are you commenting on it?
>>7657405
Clever, I had a similar idea but using a single molecule led's and manipulating the em field as opposed to scattered lasers, though your idea is better

Right, because light is magnetic...
By what mechanism can a magnetic field cause a laser beam to defocus?
Cubic lcd system, duh.

Well, http://m.phys.org/news/2014-09-defying-physics-magnetic-field.html The physics're easy enough to visualize in my mind, but more info pertinent to the modules would help.
