Abstract
An apparatus, system, and method for a waveguide system may be used to support eye tracking in a head mounted display (HMD). The waveguide system may be positioned in a user's field of view and within a lens assembly of the HMD to capture light that is reflected from an eye. The waveguide system may include a holographic optical element (HOE) configured to in-couple light into a waveguide and direct the light to an out-coupling grating. The HOE may be configured to map a number of incident light rays to a corresponding number of total internal reflection (TIR) angles. The incident light rays may include at least some oblique light rays that are non-normal to an input surface of the HOE. The HOE may have a field of view (FOV) of an eyebox region that is at least partially outside of a periphery of the input surface of the HOE.
