FIELD: optics.
SUBSTANCE: device is used for displaying graphic images. One of variants of its realization includes holographic diffraction picture 100, positioned on constant magnet 120 or element connected to it, and coil or wire 160, through which current is let for moving the magnet. Rotation of holographic diffraction picture relatively to axis 10 forms an image using light, diffracting on holographic diffraction grid. Other variant of realization of display includes faceted rotary element, including facets matrix, each of which contains diffraction grid, and drive, meant for rotation of faceted rotary element from idle position to observation position. Rotation of faceted rotary element leads to forming of image by diffracted light.
EFFECT: broader functional capabilities.
