A device for generation of a flat light diffusing medium, consisting of a chamber (1) generating a projection screen (2), fans (4) to blow air, and channels (6) guiding an air-curtain (7), characterized in that the air-curtain (7) and projection medium (2) guiding channels (6) are arranged side-by-side and connected with each other so making up a sheet of channels. Plural of these sheets are situated one over another in a way that making up channels (6) that are situated non- coaxially one over another to provide for a better guidance and stabilisation of the air-curtain streams (5) as laminar streams. |
