FIELD: physics.
SUBSTANCE: optical device for forming an image is made from two or more layers and has a light-reflecting boundary surface and a light-transmitting boundary surface. The light-reflecting boundary surface is provided with a first relief structure having two-dimensionally arranged first recesses or protrusions, and emits a first diffracted light when illuminated with light. The light-transmitting boundary surface lies in front of the light-reflecting boundary surface and has reflectance smaller than that of the light-reflecting boundary surface, is provided with a second relief structure having second recesses or protrusions arranged two-dimensionally, emits a second diffracted light when illuminated with light.
EFFECT: providing a special visual effect.
