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.
Claims14
A lens system for use with an image display system having a miniature image source operative to provide an image separate from ambient light, the lens system comprising:
- at least a first lens having two optical surfaces arranged to permit passage of some ambient light by the first lens through the two optical surfaces;
- an optical pathway disposed internally within the first lens to receive light from the image display system separate from the ambient light, the optical pathway having at least a portion disposed along and between the two optical surfaces of the first lens;
- and
- an insert disposed internally within the first lens, the insert comprising an interface disposed to redirect light, which has passed along at least the portion of the optical pathway, out of the first lens to a user's eye.
