In this publication, we are demonstrating for the first time ever how a curved waveguide can be used as a combiner for head up display or augmented reality applications. We used holographic optical elements to correct for the distortion of the image during its propagation inside the curved waveguide. The image is extracted from the waveguide multiple times to expand the system pupil and offer a large eye box. The image that is perceived by the viewer does not show any aberration, and is projected at infinity so it does not require any accommodation. In addition, we are using a polymer waveguide, instead of glass, which reduces dramatically the cost of the system.
