Mid air screen

Hi I'm writing in the hope to make a barrier using ultrasound, a cross section creation that is powerful enough to hold or keep some of the light in place, enough to see some kind of image or outline of instance of it working (New type of screen) . I've read that ultrasound can be used to stop light. Saying that, the type or frequency used wasnt mentioned. Only that ultrasound was used in an array type format. Another section of this topic I've read is the use of Non-reciprocal Brillouin scattering induced transparency which is used for controlling light propagation in a dielectric medium, and for producing slow and fast light, one of the mediums in order for this to work is the air around us. Is there a way of holding the light using ultrasound, in the ways specified above and how exactly would someone go about in doing this. If not, Is there a way of sustaining light in a the air without using fog or a Literal material. [login to view URL] Ps. Bristol University | News | December: Haptic shapes using ultrasound - They've created shapes using ultrasound in the air (not vivible ones, touvhable ones) . I want to know that whether using a system similar to the array that is used on the example above, whether the scale is too small or not, can result in the theory becoming a reality. I would like to create this prototype in order to create a new type of screen or PC. I've asked many people with experience some of them sayid is impossible others said is possible but you will need a bit more than a ultrasound.I know can seem to be impossible but I'm willing to pay good rate if you can deliver the project. Thank you for your time Cheers Had
