FIELD: displaying.
SUBSTANCE: invention relates to apparatuses generating "floating" images in the open space. Apparatus comprises a projection optical system; a waveguide containing a first input diffraction optical element, a second input diffraction optical element, an output diffraction optical element, and an optical element with positive optical power. The projection optical system includes: an image projector, an optical transfer unit, an intermediate image area, and a projection unit.
EFFECT: user of the invention observes a real image in space in a large field of view during use.
