The authors studied the retinal projection AR display's eyebox expansion, which may cause image deviation.They propose an eyebox-extended retinal projection display with gaze-matching for AR.The system's exit pupil is a composite image combiner using three holographic optical elements (HOEs).Each HOE is positioned at a specific location on the waveguide.Simulation and experimental results have proven that the proposed system can project virtual images onto the fovea of the human eye to achieve gaze-matching.
