An input-coupling holographic grating with lens function is presented to effectively replace the required projection lens in a grating-based waveguide display system. The overall system size and weight of the waveguide display system is effectively reduced. A see-through green-color image with FOV of 34.6° × 55.0° (H × V) is obtained.
