Abstract:     An optical system combines a first image formed by a main lens with a second image provided by an electronic display, slide, or other image source. The image combining system includes one or more inserts such as a set of reflecting image combiners to redirect light on an optical pathway within the main lens to the user's eye. The image combining system is highly compact, allowing the integration of a display system with eyeglasses or a face mask, such as a diver's mask. A number of implementations of the optical system make possible other types of image integration including uses in image acquisition systems such as cameras.

First Claim:
Show all 114 claims		 What is claimed is:     1. A head-mountable image combining lens system for mounting on a user's head for use with a user's eye, the head-mountable image combining lens system comprising:
  • a support frame configured to be supported by the user's head;
  • a lens system supported by the support frame in front of an eye of the user 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 an image source 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; and
  • a further portion of the optical pathway, the further portion of the optical pathway supported by the support frame and disposed to direct light from the image source to the portion of the optical pathway disposed internally in the lens system.
