APPARATUS FOR GENERATION OF A VOLUME OF FREE AIR ADAPTED FOR PROJECTION OF IMAGES ON NON- SOLID SCREEN

摘要

An apparatus for generation of a volume of free air (15) adapted for projection of holographic images comprising a blowing device (12) fed with an nebulized air-water mixture generating a substantially flat laminar flow of said mixture through an outlet orifice (18) and along an advancing direction; said apparatus further comprising a suction device (13) for the mixture forced into a laminar motion, placed downstream of the blowing device (12) relative to the mixture advancing direction, the suction device (13) being provided with a mixture inlet orifice (20) facing the outlet orifice (18) of the blowing device (12), the distance (D) of these orifices (18, 20) being such that the mixture flow from the outlet orifice (18) to the inlet orifice (20) is substantially of laminar type.
