Planar waveguide apparatus with diffraction element(s) and system employing same

This invention describes a system of multiple transparent plates, each designed to guide light internally and use special patterns (diffractive optical elements) to direct light in and out. These patterns can shape light beams to create focused images, potentially for augmented reality systems where digital images are overlaid onto the real world. The core claims specify an *array* of these waveguides, with the special patterns either integrated or placed between the plate faces.
