Abstract:
1. A wearable display system which combines a synthetic image with a contemporaneously viewable real image of the outside world, said system comprising: a. a display engine which produces linearly polarized light defining said synthetic image; b. a light engine which produces light to illuminate said display engine; c. a polarizing beamsplitter in the path of said light produced by said light engine, said polarizing beamsplitter polarizing a portion of said light from said light engine and reflecting such polarized portion of light onto said display engine to enable said display engine to produce said linearly polarized light defining said synthetic image; d. display optics in the path of said linearly polarized light defining said synthetic image; and e. a wire grid polarizing combiner through which said real image is contemporaneously viewable, said display optics relaying said linearly polarized light to said wire grid polarizing combiner, and said wire grid polarizing combiner reflecting said linearly polarized light such that said synthetic image is overlaid onto said contemporaneously viewable real image.
