Method and device for generating spatial images

摘要

The invention is related to methods and devices for generating spatial images. The method comprises forming at least two directional radiation beams in a selected viewer's plane, each of the at least two directional radiation beams having a power from 0.05 to 10 of a human eye differential threshold for a current viewing condition, and directing at least two directional radiation beams to intersect and form a light spot at a crossover point, the light spot having an angular dimension corresponding to an angular resolution of a human eye and making the light spot visible from any point within the viewer's plane. 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.
