| 摘要 |
The invention relates to a method for producing a non-solid projection screen (3), projection volume (8), or the like, the method comprising the steps of supplying and/or forming light scattering/reflecting scattering centres (4) to a substantially laminar transfer flow (2) to be transferred by said transfer flow (2). In accordance with the invention, the scattering centres (4) are supplied and/or formed to the transfer flow (2), to the central/inner parts thereof that remain laminar, away from the direct vicinity of the interfaces between the transfer flow (2) and the area surrounding thereof, in order to keep the projection screen in shape. In accordance with the invention, as the scattering centres (4) can be used light elastically or non-elastically scattering, solid liquid or gaseous substance. |
