Abstract

A flat panel, compact virtual image projection display is presented. It is based on a light- guided optical configuration that includes three linear holographic gratings recorded on one planar transparent substrate so as to obtain a magnified virtual image for a small input display. The principles of the projection display, unique design, and procedures for experimentally recording an actual planar configuration are presented, along with evaluation results. The results reveal that a field of view of $\pm 8°$ can be readily achieved at a distance of $36\text{\hspace{0.17em} cm}$, making such planar configurations attractive for head-up displays.
