Abstract: A head mounted display system can include a camera, at least one waveguide, at least one coupling optical element that is configured such that light is coupled into said waveguide and guided therein, and at least one out-coupling element. The at least one out-coupling element can be configured to couple light that is guided within said waveguide out of said waveguide and direct said light to said camera. The at least one coupling element may comprise a diffractive optical element having optical power.

Abstract: Methods and systems for depth-based foveated rendering in the display system are disclosed. The display system may be an augmented reality display system configured to provide virtual content on a plurality of depth planes using different wavefront divergence. Some embodiments include monitoring eye orientations of a user of a display system based on detected sensor information. A fixation point is determined based on the eye orientations, the fixation point representing a three-dimensional location with respect to a field of view. Location information of virtual objects to present is obtained, with the location information indicating three-dimensional positions of the virtual objects. Resolutions of at least one virtual object is adjusted based on a proximity of the at least one virtual object to the fixation point. The virtual objects are presented to a user by display system with the at least one virtual object being rendered according to the adjusted resolution.

Abstract: A head mounted display system can include a camera, at least one waveguide, at least one coupling optical element that is configured such that light is coupled into the waveguide(s) and guided therein, and at least one out-coupling element. The at least one out-coupling element can be configured to couple light that is guided within the waveguide(s) out of the waveguide(s) and direct the light to the camera. The at least one coupling element may include a diffractive optical element having optical power. Additionally or alternatively, the at least one coupling optical element may have a coupling area, for coupling light into the waveguide(s), the coupling area having an average thickness in a range from 0.1 to 3 millimeters across and/or may have a pinhole sized and/or slit shaped coupling area.
