Patent abstract

An event camera system for pupil detection may include a camera assembly and a controller, and may also include one or more off-axis light sources. The camera assembly may include one or more infrared (IR) light sources and an event camera. The one or more IR light sources are configured to emit pulses of IR light along an optical path toward an eyebox. The IR light is reflected from an eye in the eyebox, and the reflected light propagates back along the optical path toward the event camera for detection. The controller is configured to determine an orientation of the eye using data output from the event camera.
