FIELD: physics; optics.
SUBSTANCE: presented is an optical device with a light guide substrate, with at least two surfaces which are parallel to each other, an optical apparatus for input of light waves into the substrate through internal reflection, and at least one partially reflecting surface, placed on the substrate, which is parallel the above mentioned two substrate surfaces. One of the two surfaces has an angular selective coating.
EFFECT: design of a compact display system with improved operation characteristics.
