AI Technical Summary
Technical Problem
Existing tunable lenses for head mount wearables, such as glasses and AR/VR systems, face challenges in efficiently actuating non-circular lens shapes, which are desirable for aesthetic, mass, and nose clearance reasons.
Method used
A lens design featuring a non-circular lens shaper with a movable structure that includes actuation points or sections located within a virtual hollow cylinder volume around the optical axis, allowing for efficient deformation of the membrane to adjust the optical power of the lens.
Benefits of technology
The design enables efficient and simple actuation of non-circular lens shapes, allowing for precise adjustment of spherical and prismatic powers, while maintaining zero power consumption when maintaining a tuned state.
