Planar optics enables chromatic aberration correction in immersive near-eye displays

摘要

We demonstrate an optical chromatic aberration correction method for virtual reality (VR) displays using cost-efficientflat optics. The fabricated ultra-broadband liquid crystal thin-film polymer lens is based on the Pancharatnam-Berry phaseand manifests over 97% first-order diffraction efficiency over the display spectrum. By cascading the fabricated polymerlens with the conventional Fresnel VR lens, the lateral color breakup in the near-eye display system can be reduced bymore than 10 times. Both optical designs and experimental results are presented and discussed.
