SYSTEM FOR GENERATING A SPATIAL IMAGE IN A LAMINAR AIR FLOW Russian patent published in 2023 - IPC G03B21/60 

FIELD: imaging.

SUBSTANCE: invention relates to electromagnetic apparatus for generating a spatial image in a jet of the laminar flow of a gas medium. A display reproduces an image in a jet of laminar air flow by adding mist to jet sections in the flow. The system includes a box, an apparatus for generating a spatial image, a fan unit, an air flow laminarising apparatus, and an image backlight tool. The box limits the working volume of image localisation in the laminar air flow and is configured for the image to be observable. The image-generation apparatus includes one electromagnetic valve unit. The unit comprises two tanks with a gas and/or aerosol medium; N solenoid valves (N > 1), wherein each valve has two input channels, an output channel, and a switching tool; a power supply unit and an electronic valve control unit with electronic drivers. The air flow laminarising apparatus is located on the side of the box inlet before or after the electromagnetic valve unit in order to eliminate turbulent vortices from the inlet air flow. The image backlight apparatus is placed in the box.

EFFECT: creation of a moving spatial image with controlled speed of movement with the maintained high image quality.
