Paper Abstract

Recently, augmented reality (AR) systems using holographic optical elements are getting the limelight. The holographic diffuser can be used as a screen in AR systems because it only diffuses incident light in a certain angle. To achieve a wide field-of-view (FOV), a diffusing angle of the screen should be sufficiently large. However, in the case of the holographic diffuser, it is difficult to achieve a high transmittance when the diffusing angle of the employed diffuser is large. In other words, by using conventional holographic screens, it is difficult to achieve a high transmittance and a wide FOV simultaneously. In this work, we propose an anisotropic holographic diffuser providing a wide FOV with relatively small diffusing angle by adopting a convex lens in the recording process. Furthermore, in the last section, a scheme of AR near-eye display system is suggested by using the proposed holographic screen and a special eye piece consisted of geometric phase lens.
