Holographic optics are an exciting tool to increase the performance and reduce the size and weight of augmented and virtual reality displays. In this talk, I will describe two types of holographic optics that can be applied to AR/VR, as recently outlined in two ACM SIGGRAPH publications. In the first part, I will describe how static holographic optics can be used to replace conventional optical elements, such as refractive lenses, to enable highly compact, sunglasses-like virtual reality displays while retaining high performance. In the second part, I'll describe the potential of dynamic holography to replace the conventional image formation process and enable compact and high performance augmented reality displays. In particular, I will focus on a key challenge of dynamic holographic displays, limited etendue, and present a candidate solution to increase etendue through the co-design of a simple scattering mask and hologram optimization.
Andrew Maimone is a research scientist in the Display Systems Research team at Facebook Reality Labs Research. His research focuses on the use of novel optics and computing to enhance virtual and augmented reality displays. He has published novel display designs using holography and light fields with an emphasize on wearable displays with wide fields of view, compact form factors, high resolution, and support for the accommodation depth cue. Previously, Andrew was a researcher at Microsoft Research NExT and completed a PhD in computer science at the University of North Carolina at Chapel Hill.
