Creating a virtual reality by ion beam technology

Abstract

Among the most significant technological challenges associated with augmented reality (AR) and mixed reality (MR) glasses is the production of optical waveguide combiners. For both technologies, surface relief gratings (SRG) are used as the in-couplers and out-couplers of the light into the near-eye displays. This article shows the manufacture of slanted SRGs using ion beam processing as a crucial component of the waveguide.
