Assignee: MAGIC LEAP, INC.
Field: Optics (Instruments)
Classification: CPC G | IPC F  G

Claim 5:
6. An adaptive lens assembly comprising:
a waveplate lens comprising a liquid crystal polymer layer;
a switchable waveplate assembly comprising:
a first substrate and a second substrate defining a volume therebetween, wherein the first substrate is a first quarter-wave plate and the second substrate is a second quarter-wave plate, and wherein the first substrate and the second substrate are composed of a non-liquid crystal material that is optically transmissive and pliable;
a liquid crystal layer disposed within the volume;
a first set of guides for aligning liquid crystal molecules of the liquid crystal layer, the first set of guides comprising a first electrode pattern disposed in the volume and directly on the first substrate; and
a second set of guides for aligning the liquid crystal molecules of the liquid crystal layer, the second set of guides comprising a second electrode pattern disposed in the volume and directly on the second substrate;
wherein the first electrode pattern and the second electrode pattern extend into the liquid crystal layer and are configured to selectively apply an electric field, and
wherein the first electrode pattern and the second electrode pattern are configured to:
cause a first orientation of the liquid crystal molecules of the liquid crystal layer when the electric field is not applied, to cause the switchable waveplate assembly to provide a first optical power, and
cause a second orientation of the liquid crystal molecules when the electric field is applied, to cause the switchable waveplate assembly to provide a second optical power that is different than the first optical power.
