Abstract

Offering an ultrathin formfactor and lightweight, diffractive liquid-crystal optics is a promising tool to design a more compact VR display system. However, the severe chromatic aberrations of this diffractive elements need to be solved before further practical applications. Here, we come up with an achromatic system consists of three diffractive liquid-crystal components to address this longstanding color issue. The phase and spectral response of each element are specifically designed to manipulate the polarization states of light and compensate the chromatic aberrations. A significant improvement in color performances has been demonstrated with both our simulations and experiments. Potential applications for metaverse, spatial computing, and digital twins that have found widespread applications in smart tourism, smart education, smart healthcare, smart manufacturing, and smart construction are foreseeable.
