Abstract | Disclosed is a holographic waveguide including a light guide unit configured to guide lights; a first holographic optical element disposed on one surface or the other surface of the light guide unit such that a light output from a light source is input and guided on the light guide unit and configured to diffract an input light; a second holographic optical element disposed on any one of the one surface and the other surface of the light guide unit, and configured to receive a light diffracted by the first holographic optical element and guided through the light guide unit and to direct a part of the received light to the other one of the one surface and the other surface of the light guide unit by diffraction; a third holographic optical element disposed on a surface opposite to the surface of the light guide unit on which the second holographic optical element is disposed, and configured to receive lights diffracted by the second holographic optical element and to guide the received lights to areas, which are different from areas where the first and second holographic optical elements are disposed, on the light guide unit by diffraction; and a fourth holographic optical element configured to receive a light diffracted by the third holographic optical element, and to allow the received light to be output from the light guide unit by diffraction. |
