P‐148: A Continuous Variable Lens System to Address the Accommodation Problem in VR and 3D Displays

Abstract

The focus cue is a continuing concern within the field of Virtual Reality (VR), Augmented Reality (AR) and 3D displays. Although liquid crystal (LC) based lens is an excellent candidate for tunability, a major problem with VR/3D application is a need for large aperture not inhibiting the field of view, but that also maintains a reasonable switching time. In this paper we discuss results with two systems that can be used for such application. We present the result of user preference for an approach using a Fresnel lens structure, and propose a second design that is a hybrid system comprised of refractive Fresnel and Pancharatnam‐Berry LC lenses. Our study presents a compact, large aperture, fast and tunable optic that can be used in numerous applications including VR/3D systems.
