68‐3: A Multi‐focal Waveguide Near‐eye Display Based on a Tunable Pancharatnam‐Berry Phase Lens
Bo Wang, Yan Li, Zekun Yan, Yikai Su, Shuxin Liu- General Medicine
A multi‐focal waveguide near‐eye display (WNED) system for augmented reality (AR) based on a tunable Pancharatnam‐Berry (PB) phase lens. The tunable lens is made of a stack of switchable PB lens elements which can be switched on and off by voltage. Combined with a waveguide display module, a prototype of the WNED system with images generated at different depths is demonstrated.
