Abstract: An off-axis optical combiner includes a parabolic lensing structure that selects collimated infrared image light received from an eyebox area for focusing to a focus of the off-axis optical combiner. Selecting the collimated infrared image light for focusing allows the parabolic lensing structure to form a same-sized image of an object having variable depth from the parabolic lensing structure.

Abstract: The disclosed embodiments are generally directed to optical systems. The optical systems may include a proximal lens that may transmit light toward an eye of a user. The optical systems may also include a distal lens that may, in combination with the proximal lens, correct for at least a portion of a refractive error of the eye of the user. The optical systems may further include a selective transmission interface. The selective transmission interface may couple the proximal lens to the distal lens, transmits light having a selected property, and does not transmit light that does not have the selected property. The optical system can also include an accommodative lens, such as a liquid lens. Various other methods, systems, and computer-readable media are also disclosed.

Abstract: Disclosed herein are techniques for eye illumination for eye position tracking. An illuminator for eye tracking includes a substrate configured to be placed in front of an eye of a user and a light source positioned on a surface of the substrate. The light source is configured to be positioned within a field of view of the eye of the user. A maximum dimension of the light source in a plane parallel to an emission surface of the light source is less than 500 μm.

Abstract: Aspects of the present disclosure are directed to controlling optical parameters at a user's eye using an artificial reality system and tracked user conditions. For example, based on tracked user eye positioning, implementations can adjust the light that enters the user's eye to control an image shell generated at the user's eye. An image shell refers to the way light, that enters the eye, focuses on the retina of the eye. Example properties of an image shell include image shell centration, image shell curvature, image shell shape, etc. A user may focus on an object in an artificial reality environment (e.g., real-world object or virtual object) and light from the object can generate an image shell at the user's eyes. The image shell at the user's eyes can impact the user's vision and/or eye biology.

Abstract: An optical system includes a first optical element having at least a first optical surface and a second optical surface, the first optical surface is not parallel to the second optical surface. The optical system includes a plurality of optical elements positioned adjacent to the second optical surface of the first optical element. The respective optical element of the plurality of optical elements is configured to receive light transmitted through the first optical surface at a first angle with respect to the second optical surface and direct the light back toward the first optical surface at a second angle, that is distinct from the first angle, with respect to the second optical surface.

Abstract: A retinal imaging system includes a projector, an imaging device, and a controller coupled to an eye tracking system under test. The projector emits a light pattern to be delivered to a pupil of an eye, a location of the pupil being estimated by the eye tracking system under test. The imaging device captures one or more images of a retina of the eye illuminated with at least a portion of the light pattern. The controller determines one or more eye tracking parameters based on the captured one or more images of the retina. The controller compares each determined eye tracking parameter with each of estimated one or more eye tracking parameters, wherein values for the one or more eye tracking parameters are estimated by the eye tracking system under test. The controller characterizes each estimated eye tracking parameter based on the comparison.
