Full-color optical combiner with good imaging quality and a wide angle of incident light acceptance

Abstract

This work demonstrates a full-color optical image combiner for augmented reality head-up displays. In this device, the angle of the incident light of the computer-generated image reflected by it can vary over a large range. It achieves improved performance by using a combination of polarization interference filters (PIFs), quarter-wave retarders (QWRs), and polarization volume holograms (PVHs). The details for an example design and its performance are presented.
