Holographic waveguide, method of producing the same, and display device including the holographic waveguide

A virtual and augmented reality device comprising:

• a holographic waveguide comprising:
• a waveguide element configured to guide light;
• and
• a diffractive optical element comprising an aberration correction hologram pattern, the diffractive optical element being provided adjacent to the waveguide element and configured to correct aberrations generated in the light traveling along the waveguide element by the waveguide element;
• and
• an image source configured to provide, through the holographic waveguide, an image to be delivered to a user's eye.

A method of producing a holographic waveguide, the method comprising:

• providing an inspection wave to be incident on a local structure comprising a waveguide element and a recordable medium fragment;
• detecting aberrations of the inspection wave that has passed through the local structure, and obtaining phase-conjugated aberrations with respect to the detected aberrations;
• forming a pre-aberrated object wave by imparting the phase-conjugated aberrations to an object wave;
• and
• recording, on the recordable medium fragment, an interference pattern of an aberration-free reference wave and the pre-aberrated object wave.
