METHOD AND DEVICE FOR GENERATING SPATIAL IMAGES

摘要

The invention is related to methods and devices for generating spatial images and is intended for use in the field of advertising, show-business etc. with no special measures being required for reflecting or scattering optical radiation both in the open air and in closed space. It is the aim of the present invention to design a method and a device for generating spatial images when no use is required of either image carriers or special measures for reflecting or scattering optical radiation. The above-set aim in a method of generating spatial images consisting in forming and supplying into the selected space region of a directional visible radiation beam, is achieved by means of forming at least two directional radiation beams, each having the power from 0,05 to 10 thresholds of human eye visual perceptivity for the current viewing conditions, with said directional visible radiation beams being supplied into the selected space region in such a manner that the crossover point of said beams would be located within said region, and the visible from any point within the said region angular dimension of said crossover point corresponds to the angular dimension of the human eye. Imaging is provided by means of a spatial displacement of a crossover point with an appropriate variation of brightness and/or color of said point, if required.
