Bioplastic Tunable Liquid Crystal Lenses for Dynamic Focus in Virtual and Augmented Reality

抄録

We describe a tunable liquid crystal lens based on Fresnel optics that enables variable focus of virtual images displayed by a head-worn VR or AR device. This lens has been fabricated using ultra-thin, light bioplastic film instead of glass, uniquely enhancing visual comfort whilst reducing weight and thickness compared to glass-based approaches.
