Abstract

A head-mountable image display system provides an image to a user's eye separate from ambient light. The system includes an optical relay having an optical pathway to receive light from a display element. The optical relay also permits passage of ambient light toward the user's eye. An eyepiece assembly is disposed to redirect light on the optical pathway to the user's eye. The system is highly compact, allowing the integration of the display system with eyeglasses, a face mask, such as a diver's mask, a head set, or the like.
