Abstract
A head mounted display system configured to project light to an eye of a user to display augmented reality images can include a frame configured to be supported on a head of the user, a camera disposed temporally on said frame, an eyepiece configured to direct light into said user's eye to display augmented reality image content to the user's vision field, a reflective element disposed on the frame, and at least one VCSEL disposed to illuminate said eye, wherein the camera is disposed with respect to the reflective element such that light from the VCSEL is reflected from the user's eye to the reflective element and is reflected from the reflective element to the camera to form images of the eye that are captured by the camera.
