| description | The disclosure includes optical systems and near-eye optical elements configured to suppress stray infrared light. Infrared illuminators illuminator an eyebox area with narrow-band infrared illumination light for eye-tracking. A combiner layer receives reflected infrared light reflected of an eye of the user and directs the reflected infrared light to a camera configured to capture eye-tracking images of an eye of a user. An anti-reflection (AR) coating may be disposed on a base curvature to reduce Fresnel reflections that generate stray light. A ghost suppression component may be paired with the infrared illuminators to reduce stray light becoming incident on the camera. |
