System and method for foveated image generation using an optical combiner
First Claim
1. A display system, comprising:
- an optical combiner configured to;
redirect a first set of light rays towards an eye, wherein the redirected first set of light rays produce a peripheral image; and
redirect a second set of light rays towards the eye, wherein the redirected second light rays produce an inset foveal image positioned within at least a portion of the peripheral image; and
a light engine configured to generate the second set of light rays to intersect a first region of the optical combiner and converge at a nodal point within 1 mm of a rotational center the eye and, in response to a change in a gaze direction of the eye, to offset an origin of the second set of light rays to move the intersection of the second set of light rays with the optical combiner from the first region to a second region of the optical combiner.

Abstract
A method, computer readable medium, and system are disclosed for generating foveal images. The method includes the steps of redirecting first light rays towards an eye, where the first light rays are redirected by an optical combiner and produce a peripheral image and generating second light rays by a light engine. The second light rays are redirected towards the eye, where the second light rays intersect a first region of the optical combiner and converge at a nodal point within the eye and produce an inset foveal image positioned within at least a portion of the peripheral image. An origin of the second light rays is offset to intersect a second region of the optical combiner in response to a change in a gaze direction of the eye.

20. A non-transitory, computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform steps comprising:
-
redirecting a first set of light rays towards an eye, wherein the first set of light rays are redirected by an optical combiner and produce a peripheral image; generating a second set of light rays by a light engine to intersect a first region of the optical combiner; redirecting the second set of light rays towards the eye, wherein the second set of light rays converge at a nodal point within 1 mm of a rotational center of the eye and produce an inset foveal image positioned within at least a portion of the peripheral image; and offsetting an origin of the second set of light rays by the light engine to move the intersection of the second set of light rays with the optical combiner from the first region to a second region of the optical combiner in response to a change in a gaze direction of the eye.
