Abstract
An augmented reality display system includes a first beam path for a foveal inset image on a holographic optical element, a second beam path for a peripheral display image on the holographic optical element, and pupil position tracking logic that generates control signals to set a position of the foveal inset as perceived through the holographic optical element, to determine the peripheral display image, and to control a moveable stage.
Claims20
An augmented reality display system comprising:
- an inset display;
- a half mirror;
- a concave half mirror;
- and
- a waveguide comprising the half mirror and the concave half mirror, the waveguide converting an inset image generated by the inset display into a foveal inset.
2 more elements
An augmented reality display system comprising:
- a first beam path for a foveal inset image projected through a holographic optical element, the first beam path forming a reflective magnifier lens;
- a second beam path for a peripheral display image on the holographic optical element;
- pupil position tracking logic;
- and
- the pupil position tracking logic generating control signals to set a position of the foveal inset on the holographic optical element, to determine the peripheral display image, and to control a moveable stage coupled to the holographic optical element.
