Paper Abstract

The eye-box expansion method using the merging of waveguide and HOE (holographic optical element) is presented. Using the waveguide with the refractive index of 1.7, the wide FoV (field of view) that is up to 60° is achieved. Full color and wide FoV are obtained using 2 waveguides. Projection optical system based on Scheimpflug principle is proposed and designed to compensate large-scale off-axis HOE aberrations. In order to enhance image quality, the projection system is precisely simulated and the grating pitch and alignment are calculated to increase the eye-box and uniformity.
