Facebook develops holographic optics for thin and lightweight virtual reality
Facebook Reality Labs has published “Holographic Optics for Thin and Lightweight Virtual Reality”, its latest research into making VR headsets less cumbersome and more suitable for everyday use. Its latest paper outlines a “new optical architecture that is significantly more compact and offers the potential for better visual performance”. The paper’s researchers Andrew Maimone and Junren Wang propose new near-eye display technology that combines the holographic optics and polarization-based optical folding to help keep the optics as thin as possible while making the most efficient use of space. The prototype images show a headset about the size of a chunky pair of sunglasses created using this approach, a significant size reduction compared to the smallest headsets currently on the market. Tt present this remains a proof-of-concept and is but one of several approaches being explored by Facebook to reduce the size of headsets. Read the paper in full on Facebook’s research website.
