Abstract:
An imaging apparatus has a projector apparatus that projects light for forming a first image and a second image. A first pupil expander lies in the path of projected light and is configured to direct light to a viewer to form a first virtual image at infinity focus. A second pupil expander lies in the path of the projected light and is configured to direct light through a first lens and to the viewer to form a second virtual image near a focal plane of the first lens. A second lens is disposed to condition light from a visual scene lying beyond the second pupil expander.
