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.
