摘要 An optical apparatus records light reflected from one or more of a user's facial features. While the image is captured, visible light from a display or other scene to be viewed by the user passes to the user's eye. A portable iris pattern capture device is used. Near-infrared light is directed towards the user's eye from where it is reflected back into the apparatus. Visible light from an LCD display mounted at the rear of the apparatus travels out to the user's eye from the apparatus. A hot mirror inside the apparatus directs the near-infrared light reflected from the user's eye to a camera unit, and does not significantly attenuate the visible light emanating from the display.
