DEVICE FOR DYNAMIC HOLOGRAPHIC IMAGES CREATION IN SPACE Russian patent published in 2020 - IPC G09F19/10 

FIELD: advertising and information technologies.

SUBSTANCE: device includes a light source, a laser projector, which additionally includes a unit for forming a base of a virtual screen in air, a unit of holographic plates, a logic unit and a control computer. Light source is connected to the laser projector through an optical splitter and comprises controlled drives. Unit of holographic plates is a multilayer optically transparent liquid crystal matrix consisting of separate optically transparent layers. Separate layer of optically transparent liquid crystal matrix includes two outer optically transparent plates, between which there are capillary channels with solution of optically transparent electrolyte having the same optical conductivity as outer optically transparent plates connected to external current leads and dot liquid crystal segments of separate layer of optically transparent liquid crystal matrix. On the front surfaces of each separate layer of the optically transparent liquid crystal matrix on its two optical plates on the outer side a thin film of metamaterial with a negative refraction index is applied.

EFFECT: in a block of holographic plates at different moments in time an image hologram and a hologram of a contrast virtual screen are formed, on which the image hologram is focused, and switching in a block of holographic plates of an image hologram to a hologram of a contrast virtual screen is carried out by a logic unit based on signals of the control computer, taking into account physiological parameters of inertia of human vision, which provide a cinematic principle.
