72‐4: Switchable Lens based on Cycloidal Diffractive Waveplate for AR and VR Applications

Abstract

A switchable lens based on a cycloidal diffractive waveplate and a polarization rotator is demonstrated. This switchable lens has advantages in fast response time, low chromatic aberration, and low operation voltage. Its potential applications include wearable virtual reality, augmented reality, and other headmounted display devices.

LC lens systems to solve accommodation/convergence conflict in three-dimensional and virtual reality displays

“…However, we have shown in a separate publication that with optical power less than 2-D, the chromaticy of the PPL can be considered negligible. 25 Lee et al 26 showed that PPL can provide fast response focus for augmented and virtual reality (AR/VR) application. His proposed design has the potential to switch between two planes; however, we integrate PPL with SPP LC lenses to be able to have a continuous range of focus.…”
