Abstract
Techniques disclosed herein relate to a near-eye display system. One example of an optical device of a near-eye display includes a substrate and holographic grating conformally coupled to a surface of the substrate. The substrate is transparent to visible light and infrared light and is configured to be placed in front of an eye of a user of the near-eye display. A refractive index modulation of the holographic grating is apodized in a surface-normal direction of the substrate to reduce optical artifacts in the visible light.
